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
HTTP
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.
