Tumblr started to redirect some image urls (like "[https://68.media.tumblr.com/3cb69a5025052a5190d611d26640a7a9/tumblr_n8u6mwlw1J1rwimero4_1280.png":](https://68.media.tumblr.com/3cb69a5025052a5190d611d26640a7a9/tumblr_n8u6mwlw1J1rwimero4_1280.png) [nsfw]) to "redirect" page. Almost all ids are affected (except numberless, a, 46 and 66. Also 69 not redirects _1280). Seems to doesn't work with pretty old URLs without hash. Or it's just doesn't work when post was died.
 
It's mostly usefull feature, since it shows original post where image were posted (!!!) and leaks original image size in @[==`window\['\_\_\_INITIAL\_STATE\_\_\_'\]\["image-url-page"\].photo==]@`.


 
Also seems like it's cheating a bit: it half-ignores last digit in the image name (this digit shows image position in post) and attempting to change it in "[normal way":](https://66.media.tumblr.com/0d62f431bb952c3907d895e739caf0c2/tumblr_oxkot6NuK11u2sl0oo1_r1_1280.png) leads to 404, while "[using redirect":](https://68.media.tumblr.com/0d62f431bb952c3907d895e739caf0c2/tumblr_oxkot6NuK11u2sl0oo1_r1_1280.png) it works, but showing "[same image because of its checksum":](https://68.media.tumblr.com/0d62f431bb952c3907d895e739caf0c2/tumblr_oxkot6NuK11u2sl0oo2_r1_1280.png), "[not the actual in this position":](https://68.media.tumblr.com/0fe55cb425dd123cd6fb9d229f3e4df7/tumblr_oxkot6NuK11u2sl0oo1_r1_1280.png).
