there's this thing where if you open an image from a desuarchive indexed board in a new tab and wait for it to die, 4chan-x and xt's redirecting behavior just has it copy the 16-number value straight from 4chan to attempt to reach the same image saved in desuarchive
but desu archive's images seem to have their values be 4chan's but without the last three numbers.
So 4chan /wsr/1771132408970655.jpg needs 655 omitted to turn into desu-usergeneratedcontent /wsr/image/1771/13/1771132408970.jpg

is there any extension out there that automatically omits the last three numbers in order to redirect without me having to do it manually?
if not, can someone write a quick script for me?
