When I "insert" an image into an Outlook e-mail, the size of the e-mail tends to get very large. For example, if the inserted image is 150kb the sent message is often 5mb (in this case there is only a line or two of text and the image). If I attach the file the e-mail size is what I'd expect. Can anyone explain why this is happening, and more importantly how I can insert a picture and keep the e-mail size to what it should be?
Thanks!
Is that in the RTF format? In case case you get an embedded OLE object, which contains the original data as well as the bitmap used to render the contents of the OLE object inline without initializing the app that created the OLE object (plus a few other things, like an icon, size information, etc.).
That being said, this is not a programming question.

This is the first time I ask question here,I'm sorry about my english skill.
My useage beblow:
We use websocket for server to communicat with client.The server send image to client and eachtime there just a little difference between the images.So,How to display the images with the highest performance?
I think,I can get the difference bytes from the typed array of image,and just replace them,but how to implement this?
If your server knows what is different from what came before, then it can create a transparent image that only has the different bits in it and you can just stack that image on top of the previous image(s). In the places that it is the same as before, it can just be transparent (no image data). The relatively small amount of different data should compress into a pretty small image file.
I want to insert images in dynamic-text-box(s) which should be inline.
Detail:
I am preparing an application using flash CS4; The application is just like a chat room which will show conversation the only difference in this; it will show stored messages (stored in XML file). I want to insert smiling faces (emotions) in text body (using html tags) but the problem is that image is not inline (like in chat room [yahoo, hotmail, etc.]).
I have no idea what to do......
Please paste your code where you set the dynamic-text-box.text
Make sure that you wrap the whole text in html braces, not only images.
You can embed images in any HTMLText field using the tag.
The image, however, must be loaded externally. You can't get images stored in your library.
Its good to get the solution of my problem but sad I got solution by myself :-P
The simplest solution I got is, to update my Flash CS4 to Flash CS6; in Flash CS6 text (TextField) have extra feature like TLF (Text Layout Framework). By use TLF I can insert graphics in text area and inserted graphics are inline as well.
Problem Solved :-)
I made few forms in Access 2010 and I add logo of company to the header form. This picture is .jpg and size of it is 70KB. I don't know why size of .mdb immediately increased from 4MB to 12MB? (few forms and the same logo) Maybe there is some options of image compression ?
Taken from http://office.microsoft.com/en-us/access-help/store-images-in-a-database-HP005280225.aspx
..."However, embedding images can rapidly inflate the size of your
database and cause it to run slowly. This is especially true if you
store GIF and JPEG files, because OLE creates additional bitmap files
that contain display information for each of your image files, and
those additional files can be larger than your original images. In
addition, this method only supports the Windows Bitmap (.bmp) and
Device Independent Bitmap (.dib) graphic file formats. If you want to
display other common types of image files, such as GIF and JPEG
images, you have to install additional software."...
To explain how these bitmap files are stored, the link below offers more explanation than the microsoft site:
Taken from http://www.ammara.com/support/kb/showkbe5cc.html
..."OLE Linking & Embedding is a technique used by Microsoft Access to
store 'Objects' in database tables.The technique relies on the
associated external application to store, present and edit the data.
In some cases an additional uncompressed 'preview' image is also saved
in the table (even when linking). This preview image is used for
faster display of the data, or when the server application isn't
available. This can cause a massive overhead. If you're storing jpeg
images the uncompressed preview can be ten or twenty times the actual
image size, causing the size of the database to rocket."...
So, when you drop an image onto a form in MS Access, uncompressed image data is saved to the system tables. This is actual uncompressed table data, so a compact and repair may offer little help.
The common workaround seems to be store the path to the image in a database table, and use that path to invoke the image on the form.
I don't know WHY (and I don't care) but I already noticed that behaviour as well. My workaround for company logos or equivalent is to insert it in ONE form, which I then insert as a subform wherever I need it. It has the added benefit that if the logo changes one day, there is only one place to update.
I'm not a VB6 developer so excuse me if I'm not making any sense.
If I have a VARIANT array of bytes containing an RGB array of image data, is it possible to get that data to be displayed in a PictureBox? The PictureBox documentation suggests that the only acceptable sources are files.
Additionally, the image size and other image information is known.
The PictureBox documentation lies. But unfortunately, it’s not pretty to create an IPictureDisp in memory. The following link may help you – unfortunately, it’s in German:
How to create a picture from data in memory
There may be a better (i.e. faster) method, but you should look in to the PSet method of a picture box control.
PSet method of picture box control
hi i created a dialogbox using MFC dialog..
using below url i displayed a bitmap picture in a dialog box.
http://www.functionx.com/visualc/applications/displaybitmap.htm
i have not write any code for that.i just added the bitmap Picture into import picture dialog box and used picture control and followed the tutorial...
when i run my application it displays image...
now i would like to know is it possible to do pixel manipulation using this image...
why i ask this means i have not write any code for the display of image...
pls clarify me in this regard....
Thanks a bunch
GetDIBits() and consorts is what you're after. Quite frankly, win32 image and DC manipulation is a rather advanced subject and you'll need to put in a lot more work than following a tutorial for getting it right. Start by reading the msdn docs for GetDIBits() and related functions, then read the relevant sections in the Petzold, then read all articles that mention GetDIBits() on codeproject.com. That should teach you enough to do low level bitmap manipulation.
Alternatively, phrase your question better (i.e., explain your problem and what you want to achieve) and maybe there's a quick and dirty fix that someone can offer you.
There is I recall a Win32 API to load and decode bitmaps.
Once you have the bitmap in memory an as RGB buffer, you can modify it. You will then need to emit the modified buffer as a new bitmap, which again the API will do for you.
Be aware of course that having a bitmap in memory where you then wish for example to increase the dimensions of the image will require appropriate buffer manipulation - there is no Win32 API for generalized bitmap editing.
