Re: [twitter-dev] Re: What You Put In Not The Same As What You Get Back Out
Uploading the same file to Twitter twice in a row results in 2 unique URLs. For example: http://a3.twimg.com/profile_background_images/63273103/avatar-200.png http://a3.twimg.com/profile_background_images/63273237/avatar-200.png So after you upload the background image save the URL and either do HEAD request to see if it is still active or compare it to the URL in users/show.

I've noticed that you keep the filename. That was kind of annoying for other reasons: http://groups.google.com/group/twitter-development-talk/browse_thread/thread/1f63694495c02ff/a713748c19c35895 If I just check the filename, I can't be sure that the file wasn't changed by the user. It would be nice if the account/ update_profile_background_image function could guarantee that the image URL returned was the actual image I uploaded.

I want to be able to figure out if they are still using the background image at some future point in time. The filename might work as a test for this, instead of the computationally expensive MD5 on an image hack. We still retain the original file (basename) on images. -j --- John Adams (@netik) Twitter Operations j...@twitter.com http://twitter.com/netik

My application uploads a background image on a user's behalf. I want to be able to figure out if they are still using the background image at some future point in time. -- Kyle Mulka Founder, Congo Labs http://twilk.com On Dec 30, 5:02 pm, Zac Bowling wrote: > Twitter has to host those files.
