What is the URL schema of Tumblr images?

Question

What is the schema of a image-file at Tumblr? (I don\'t mean HTTP) I\'ve only figured out that the domain of the servers where images are stored is

Answer 1

Do keep in mind that original files (in their full resolution) are stored with the '_raw' suffix, instead of _1280, _500, _250, etc.

They are usually stored on data.tumblr.com currently (their CDN domain).

The path in the URL scheme is generated from the original (raw) file's SHA1 checksum.
