I m using latest php sdk. I can post to wall with this api. message,picture can be posted to user wall. But the picture is as thumbnail and as link.
Bu I saw some apps on facebook which post full image in wall.
How can I do this. So that PHP genered image can be posted to user wall with full size.
thanks
You probably want to look into Explicit Sharing on open graph actions. By marking an action as explicitly sharing, the post is treated like a status update and has a chance to be shown as a standalone story with a full size picture (such as Instagram, Foursquare, etc.)

I want to only allow images that are taken directly with the phone’s camera on my website. Are there any APIs or tricks that could help me tell if an image is authentic and taken with an iPhone or Android camera a few moments ago and not taken from Google Images.
Hi drstuggels they are a few ways to go about this.
WebRTC
To prevent upload from any file, take picture directly on your web interface, via the user webcam.
You would need to
Ask permission to the user to use the webcam.
Open the video stream
Capture on click the frame
Save the frame
This would prevent lambda users from uploading picture "not live".
If this is a solution you are considering, look for WebRTC. Although there are many blog post showcasing demo for this exact use case.
Such as:
https://developer.mozilla.org/en-US/docs/Web/API/WebRTC_API/Taking_still_photos
EXIF validation
As mentioned by iѕєρєня, you could try to access the EXIF metadata of the uploaded picture and run a validation mechanism, for let say freshness but looking for date and time field (if you are looking for a newly taken photo) or the camera model field to make sure it was taken by a camera (phone, DSLR, etc..).
DISCLAIMER:
Nothing will prevent a malicious user from tampering with the js code or file to upload fake picture.
See the one that comes back from
https://api.linkedin.com/v1/companies/id=1337:(id,name,logo-url)
it's quite small! https://media.licdn.com/mpr/mpr/p/6/005/056/054/057ffb7.png
Would be great if could get a larger version
(note, the apigee console here may be helpful)
The information you're looking for is in the member profile field documentation on LinkedIn's developer website: https://developer.linkedin.com/docs/fields/basic-profile
picture-urls::(original)
A URL to the member's original unformatted profile picture. This
image is usually larger than the picture-url value above.
It's been few days I'm looking for a solution and I can't figure out why it's still not working.
Here is my goal:
I have a website with a sideshow. The images are dynamically changed (with previous and next buttons). I just want to share an image on social networks (facebook, google+ and twitter) and actually see the image in my wall with a little description and the link to a page.
Precision:
The image is a thumbnail (so, not the same url) of the main image and the link I want to publish is neither the page I'm on (which is static due to Ajax) nor the image one.
My tries:
I have almost got it on facebook but the image loading failed and it was with a share button (which seems to be deprecated in favor of like) and for google+, the +1 button become red after I click it... I tried XFBML and OpenGraph, but the problem is with Ajax (url is the one of the page or is not changed even with createElement("
Questions:
1. Is there any packaged solution (like addthis, but working the way I want)?
2. Or do you have one (or a clue) for me please?
3. Am I the only one to think that offical facebook and google+ ajax documentation are lame?
Thanks a lot.

PS: if I could have a fly-out to edit a comment with the content I'm about to share, it would be fantastic!
One way to accomplish this is with cloaking.
Setup a page which provides the image, title, and description to the social application (aka. facebook, google+). You can then use Javascript to redirect the user to the page you actually want the user to see. For users without Javascript the page should display a link to the target page with a "Click here if you are not automatically redirected". The image should exist on the page but you can place it in a div with style="display: none;" so the user doesn't actually see it.
A more advanced technique would be to use the IP address and browser name (user agent) to determine if the visitor is a user or a social network robot and using a 502 temporary redirect to the page you want the user to see if the visitor is not a social robot. The social robots would be shown a page which has the image, title and description.
The social sharing buttons that you're using all have one thing in common: they all work best when there's a URL representation for the object that you're sharing. Some of them, namely Facebook's like button and Google's +1 button, use the contents of that page to create the snippet that's shared.
This isn't a new problem, though. This is the same problem faced with search indexing of AJAX applications. Sadly there's no easy solution. Here are a couple of challenging ones:
Programmatic Solution
You can improve your back end so that it's capable of rendering pages for each shareable step in the state of your slide show: one page per image. As you step through the slide show you can destroy and re-create the social sharing plugins each time targeting them to this machine accessible version of that image.
Snapshot Solution
You can use a crawler tool that is capable of executing JavaScript to make snapshots of the different states of your application. You can then target the social sharing buttons to the snapshot of the current state.
This might require less back end work but may be challenging to keep up to date.
I am trying to get Music Artist images and Album Art information from Wikipedia. Has anyone tried this before?
I searched around and found few links with relevant information
http://commons.wikimedia.org/w/index.php?title=Special:Search&ns0=1&ns6=1&ns12=1&ns14=1&ns100=1&ns106=1&redirs=0&search=buitenzorg&limit=10&offset=0 - search images for buitenzorg
http://www.mediawiki.org/wiki/API:Allimages - All images API call to fetch image urls from wiki
But could not find a way to download all the images from Music category and run deltas for updates after the initial download. Any pointers to the solution will be helpful.
I searched everywhere and finally I went with below mentioned implementation.
Here's the api documentation: http://www.mediawiki.org/wiki/API:Main_page
Call wikipedia API for artist page
Look at the player card info given on the right, and get the image name.
Make another wikimedia call to get Image download url.
Download the actual image.
For deltas, the only way is to hit wikipedia APIs again with image name and check for updates.
The other work around for this is setting your own wikimedia server, which will handle deltas.
See here http://www.mediawiki.org/wiki/Manual:Installation_guide
Google provides an excellent way to resize images dynamically; simply append =sXX to the image URL. This is perfect if you want to shrink an image, but if the image is smaller than the size specified, it enlarges it, giving it a pixelated effect.
Is there an easy way to say "don't enlarge, only shrink" when using serving URLs with a specified size?
UPDATE
This functionality is now a feature request at GAE. Vote it up if you'd like to see it!
As stated in my comments above, this isn't possible.
Although I have no use of the image framework I can see how your request would be useful. May I suggest posting a Feature Request on the Google App Engines Issues BB?
After posting the request, update your StackOverflow question with a link to your Feature Request so that other users can +1 the request.
Here's the link to the GAE Issues Page. Although this is not a bug, you will need to click the New Issue button to request a feature.
What you could do is store the size of the image in the datastore so when you need the image to be a certain size, you can check in the datastore to see what size it is and add the =sXX accordingly.
