First, please relative links (use the button or remove everything before /tags in the link). Your first link is absolute and second is relative.
Second, Joey, if you don’t want to repeat absurd res situation due to system being unable to handle it, could probably just add “alternate version” to all images with “variant” and then wipe “variant”.
I replaced the tags for about 50 drawn images. I noticed that all the rest (about 110) are used solely on toys. I wonder if that is worth keeping as a unique tag for toys only.
