Describe the feature you have in mind.

Gallery is an Abnormals' mod that adds some features related to paintings including custom icons for each painting.

It'd be great if the Vidicating Bad painting could be given a custom icon with Gallery too.

Currently, out of the ~150 paintings in my modpack, Oreganized (and Enderscape) are the only mods without support for Gallery, which is a bit annoying.

Does this solve a particular problem?

Yes, it improved compatibility with Gallery and modpacks that contain it

1.21.1 Neoforge btw

Also Vidicating in the painting's title is probably a typo and should be corrected to Vindicating
