I am trying to insert an image in Google Colaboratory (markdown) already saved in Google Drive using this expression  but it doesn't work. For example, the Colaboratory markdown manual shows how to insert a photo inline with this example An inline image: . Ok, that is a photo from internet, but, when I replace that photo for one already saved in my Google Drive it doesn't appear.
If you have a link like this, then I've got a solution.
https://drive.google.com/file/d/-------/view?usp=sharing
In Google Drive, right-click on the picture
Choose 'Get a sharable link'
Click to 'Copy link'. You need reader permissions. Just need the id of the image.
In my case my link is:
https://drive.google.com/file/d/1xDrydbSbijvK2JBftUz-5ovagN2B_RWH/view?usp=sharing
Now we need to copy JUST the image id:
1xDrydbSbijvK2JBftUz-5ovagN2B_RWH
We will use this base link to generate your link with the image id:
https://drive.google.com/uc?export=view&id=your_id
We then copy the id in the link:
https://drive.google.com/uc?export=view&id=1xDrydbSbijvK2JBftUz-5ovagN2B_RWH
Finally, to place as an image in Google Colab:
I tried all the answers above and nothing worked because of a small change Google has created recently(at the time of writing this post). If you click on "Get Shareable link" and paste it, it would look something like this:
https://drive.google.com/open?id=12BumFEqzKxc9mog8tYuUqvpxf10ot6W3
Now just change the open?id to uc?id and it will instantly work.
According to the answers here
From the next 3 formats only the first one worked for me:
Here is an example using plain html instead of markdown.
<figure>
<center>
<img src='https://drive.google.com/uc?id=1Rb6oXW3KufLApvID5MwxsknpoON2CkQ_' />
<figcaption>Image Caption</figcaption></center>
</figure>
This way, you can also center the image, add captions etc
Unfortunately, I have tried the methods above but they didn't work for me. Then I have tried simply right-clicking on the picture that I want to display on colab, and choose 'Get a sharable link', then the link is automatically copied to my clipboard:
The link will be something like
https://docs.google.com/uc?id=-----
Then using colab's picture inserting button, and insert that link to the (https://) part
worked like a magic!
However, if you get a link like this
https://drive.google.com/file/d/-------/view?usp=sharing
after making picture public, it somehow doesn't work.
This below method works for me:
Upload the image on google drive.
Enable link sharing (Right click on image > Get shareable link)
Change access type from 'Restricted' to 'Anyone with link', keep role as 'Viewer', click 'Done'(pop up should close).
Double click on image, Spot 'More actions' icon(top right corner, 3 vertical dots).. click on it and next select 'Open in new tab' from the more action menu, a new windows opens.
Now again, spot 'More actions' icon(top right corner, 3 vertical dots).. click on it and select 'Embed item'. It will give you a HTML 'Embed snippet'.
Copy that HTML snippet and paste it in your Colab noteboook inside a markdown or code cell.
If you use a code cell, you can use magic function %%html (change iframe width and height for your needs).
%%html
<iframe src="link_placeholder" width="600" height="300"></iframe>
I tried all of the above methods, and nothing works for me. However, there is a workaround that bypasses the use of Google Drive altogether: Simply insert the image as Base64 data in normal HTML like so:
<img src='data:image/png;base64, ...lots of base64-data.. style="max-width:100%;" />
If you, for example, are using draw.io to draw a diagram that you want to include, there is a handy option for embedding data (under file->embed). If you choose "image" in this menu, you'll get a pop-up with the relevant code for you to copy. Otherwise there are image to base64-converters online that you can use.
The downside of this method is that you'll end up with a lot of data to paste. However, if you use a dedicated cell for this purpose, there won't be any need to edit that cell ever again.
(As a side note, this method works in most Markdown editors if you for some reason are unable to include an image file. Sometimes it will also work to use SVG data instead of base64, but this does not work in Google Colab.)
Here are my solutions. I liked the first one more.
First Solution :
Step1: First use a wget to fetch the picture, do not use svg file! just png
!wget https://upload.wikimedia.org/wikipedia/commons/thumb/3/38/Jupyter_logo.svg/207px-Jupyter_logo.svg.png
Run the code
Step2: Get the name of the file from last line '207px-Jupyter_logo.svg.png', after you run the wget.
from IPython.display import Image
Image("207px-Jupyter_logo.svg.png")
Run the code!
Second Solution:
use the code below and use png file
from google.colab.patches import cv2_imshow
!curl -o logo.png https://colab.research.google.com/img/colab_favicon_256px.png
import cv2
img = cv2.imread('logo.png', cv2.IMREAD_UNCHANGED)
cv2_imshow(img)
So enjoy :)
Solution for svg or other type of files
Anyway, use your link :)
3rd from Github_md_guideline
Once you get the public URL of the image, you can insert it in a Markdown cell
With
Or in a Code cell (this trick is just in Colab, as far as I know)
With
##markdown 
So you can have Markdown within a code cell.
Link to shareable image is restricted to unique code associated to that picture. Once you update the picture (happens), then you need to update the link too.
Alternative ways are described here . My solution is given there too, so I will not copy past it here.
You can simply copy the picture in the clipboard and paste it in a markdown cell
With the common dialog control, lets say I set
.Filter = "Text (.txt)|*.txt|Comma Separated (.csv)|*.csv|Excel (.xls)|*.xls"
If the user does not explicitly type .txt or .csv or .xls but just enters a filename, how does one know WHICH extension they want it saved as?
As you have noticed, FilterIndex can unfortunately only be used to specify the default filter, and the Common Dialog Control will not actually give you the filter selected by the user.
I too had to do the same and switch to the Win32 API version. Here's a well written example and goes into great detail about the use of the GetSaveFileName() API and OPENFILENAME structure:
http://www.jasinskionline.com/windowsapi/ref/g/getsavefilename.html
At which point, you can use the filebox.nFilterIndex parameter after the GetSaveFileName() call to see what the user had actually selected.
In an Xpage running on Domino 9.0.1 I'm using a rich text control with some custom toolbar configuration using the control's "attr" property as it is described here: https://frostillic.us/f.nsf/posts/quick-and-dirty-ckeditor-toolbar-setup-for-xpages
I added the link toolbar template using
<xp:this.attrs>
<xp:attr name="toolbar">
<xp:this.value><![CDATA[[["Link", "Unlink", "Anchor"]]]]></xp:this.value>
</xp:attr>
</xp:this.attrs>
All three buttons are displayed fine, esp. I'm able to define an anchor link target.
But trying to reference the anchor target I find that the Link dialog is somewhat incomplete as I can't define my link to use a relative target on the same page. I tried entering a reference in the dialog's URL field as #myAnchorId, but that results in a link looking like this:
....
Here's an image of the dialog that pops up from my Xpage when I hit the "URL link" button:
And this is what the dialog looks like that I can test from the CKEditor Samples page:
I'm aware that the samples page uses CKEditor V 4, so the dialog is somewhat different, but even V 3.6 should be able to reference anchor links using the dialog.
I already looked up on the installed ckeditor's version; \DominoData\domino\html\ckeditor\version.txt says:
cke_version=3.6.6.2
cke_revision=20130606-1534
Question is: what's missing here? Do I have to somehow modify the dialog?
Oh my, finally got it to work; #IBM: this feature truly could use some proper documentation! I'll mark this answer as a community wiki.
Indeed a different dialog is used here, which btw appears to apply to all the dialogs in use with Domino's CKEditor implementation. The trick in my case is to use one of the custom toolbar items instead of the standard one; up to now I found three of those customized items:
use MenuLink instead of the standard Link item; this item
consists of two sub items ('URL Link' and 'Anchor Link'), each calling its own dialog version; the resulting toolbar definition then looks like this: ['MenuLink', 'Unlink', 'Anchor']
use MenuPaste instead of the standard Paste item; again, this
item consists of two sub items ('Paste' and 'Paste as text'), again
each calling its own dialog version
use LotusSpellChecker to add IBM's own spell checking feature, where CKE's standard spell checker isn't working
I found hints to those three custom items inside my local \DominoData\domino\html\ckeditor\config.js. Don't know if those are all custom items available to day.
EDIT:
IBM's Domino Designer Xpages User Guide mentions another means of customizing the toolbar; the section unfortunately is incorrect in describing the options for the toolbarType attribute: be aware that all named types must start with capital letters, e.g. Basic, Slim, Medium, Large, Full, while the also mentioned Lite type isn't working at all; mistyping or using a non-existing value results in the editor not being displayed at all.
The link dialog that you're using is not the default one, so you should check how to modify it or replace it with the default one.
I have a Rich Text control bound to a Body field in my Domino Document data source ... all is good for formatting text , :) emoticons and the usual stuff. The problem is when I try to paste or upload an inline image I get the following error shown in the inline image (hmmmm, works here) ...
Most likely a mis-understanding of the steps:
Select the file
Click on upload image (<-- that one gets lost on lots of users)
Click OK
For a more advanced user experience:
Use the RichText Editor Evolution from OpenNTF. That makes your life much easier.
I am using Joomla and Seblod. I would like to create a gallery of thumbnails only, tiled next to one another and when clicked it will open each image into a lightbox (fancybox) and display larger image and description.
Problem I'm having is that when I try to display only the image thumbnails, I get the label "Image" or whatever I enter into Seblod. I just want plain image thumbnails, no text or any description but when clicked it opens them in the lightbox. I'm sure this is child's play, but confusing for a a beginning Joomla user like myself.
Any help would be appreciated, thanks.
There is built-in Lightbox functionality in Seblod, but it takes a few steps to make it work. It is even better if you use a custom template, because then you can add regular PHP functions to process your photos.
In any case, to get started, look at the tutorial I wrote on this subject: http://www.seblod.com/support/documentation/seblod-2x/fields/typo/1710-create-a-simple-gallery-with-fieldx-field.html
