Hi, I was wondering HOW url of profils images were generated. So, I made some researches by myself. You'll see in this image what I learned : http://beaufort.francois.googlepages.com/Sanstitre.PNG
Can you help me to understand ? Thx!

In all likelihood, the token at the end of the URL is just a base64-encoded ciphered version of a structure that will contain the photo id.
I would be surprised if it wasn't something along that line, and if Google wasn't using some high-grade cipher algorithm, such as AES.

Which means, if I'm right, that the outer token you see in the URL just is a token with nothing to extract from (unless, obviously, you get access to the cipher key; but in that case, you would probably just have a look at the source code).
