If I post a tweet with a link to a picture it will only display the link. But if twitpic post an image link (or rather a link to a page with an image) twitter will render the image (smaller albeit).
I know twitter now has Tweet Entities but those appear to be for reading and not writing.
And yeah I could use twitpic but I rather not since we already have the images saved and ready to go.
Basically how do you become like: twitpic, lockerz, photobucket, yfrog... so on so that twitter recognizes your links as images.
Update: I know twitter will provide upload image api soon but I would rather have the image content on my site.
You can add Images to a tweet when You specify the "media_Ids" in the Api call (statuses/update). To upload media files You have to read this: https://dev.twitter.com/rest/media/uploading-media
I´m working on an automatic solution for this. It´s a bit tricky, but You can find a solutionn at time.

I had this problem too so I made an app for it (possibly overkill?). Use
http://jpg.party/SOME_IMAGE_URL
and Twitter will do the right thing and put it in a card.Twitter decides.... basically they are looking in entities / or using a regex to pick the image url out. I am not so sure about twitpic images being rendered on the twitter.com domain.... I thought they only render images through their media service.
If you are trying to avoid legal issues (in terms of who owns image) best to avoid twitpic.
The top answer to this question is out of date.
Twitter will now show an image for a link shared in a tweet if it contains the following meta info:

Twitter now has an API for what they call Cards. It is using HTML Meta tags just like the Facebook implementation.

It is only for white listed approved domain now.
