tr.rbxcdn.com

Roblox uses the listed domains to fetch user-generated images for the website. images.rbxcdn.com, on the other hand, provides essential image files to be loaded. From t0.rbxcdn.com to t7.rbxcdn.com, the images are all at the original size or the original is not publicily available. Either way, all we have left is tr.rbxcdn.com, THE ONLY DOMAIN ASSOCIATED WITH ROBLOX THAT THE IMAGES CAN BE RESIZED.

These are the references, the maximum size is 720/720 and it's universal for tr.rbxcdn.com. It's the only chunk of the URL that has to be changed in order to obtain the max image url.

Thank you very much as usual for all the research and links you provide!

I'm currently playing around with this, I'll add the 720/720 rule by itself if there's no other way, but something tells me there should be some kind of way to redirect to the original t0-7 url without brute-forcing. Especially since 0-7 = 8, which is half of 16 (hex). If not, I'll just add it to the "brute force" rule option (but keep the 720/720 thing as you mentioned) :)
