Is there any way to do this? Clicking 'Remove' on so many images gets tedious.

There is no way to mass delete images to my knowledge. What tag are you trying to remove?

Nevermind, it was discussed and decided in the thread.

I sincerely hope you aren't actually planning on deleting random files with a specific character's tag or an artist's tag. Because doing that or even just deleting the tags would be stupid for many reasons. What tag are you trying to remove anyway?

archetype it's most likely about the pen artist.
Which I explained before in a comment to another user, that deleting tags (especially artist tags) would make it much harder for other users to blacklist certain things. Which is selfish, and not one person's call to make. Polls also implied that its not a one sided decision and that people are on both sides.
Black listing tags is an easy and much simpler process/solution anyway to everyone's troubles.

I didn't know we had polls on this. But yeah, just blacklisting the tag is the best option. Removing tags hurts everyone.

Also I noticed some of pen anon's art didn't have the artist tag on them. I put it back but there might be others I need to re-tag, but searching for them is harder.

Thanks archetype, and good luck on finding those missing pieces. Retagging work right now myself.
