Hey there, I'm caching profile image urls. I'm finding quite a bit of churn, and have started wondering how I'm going to keep them up to date.
Is there anyway to predict or determine a profile image url from a screen name or something? The url's provided all seem to contain part of the original file name - which of course is impossible to guess. If there's not a way to determine them from the screen name, is there an easy way to get a bulk update of the image urls? Cheers, Tim.
