In version 1 api I could make request for user’s avatar image and get back a 128x128 image using the reasonably_small at the end of the URL, ie http://api.twitter.com/1/users/profile_image?screen_name=MarcusVincent&size=reasonably_small , this would yield a 128x128 image. However now in the 1.1 API the largest standardized image is 73x73, ie https://si0.twimg.com/profile_images/3222446743/30cb950d7b4181d809c8e9dbf9768f75_bigger.jpeg .
The reference document, https://dev.twitter.com/docs/user-profile-images-and-banners, has no more mention of reasonably_small , HOWEVER, if do use reasonably_small, it actually does return a 128x128 image, ie https://si0.twimg.com/profile_images/3222446743/30cb950d7b4181d809c8e9dbf9768f75_reasonably_small.jpeg.
So was the reasonably_small variant deprecated in 1.1 API or is the reference document not complete?
Can i continue to use the reasonably_small variant or am I playing with fire?
