What happened

After deleting the top most image in one of the boards, the board thumbnail remains stuck on the now none existent image.

What you expected to happen

The board thumb to refresh onto the next available image in the board.

This also doesnt update after a full browser refresh, engine refresh, transient files clean. Nothing seems to reset it except creating a new image.

How to reproduce the problem

Create a board Create some images Delete the latest Check the board thumbnail.

Happens mostly with assets for me.

Hello! One year has passed since this bug report was opened. Have you installed the latest version of Invoke? Currently we are at version 5.4.3! Is the problem still persistent? In the negative, and if there is no further feedback from the users, I would recommend to dismiss this bug report.

I have a different issue, I accidently deleted the thumbnail folder thinking it would be regenerated. But Invoke AI simply does not regenerate it automatically.

If you have a different issue, then you should open a new bug report.

This bug report should be closed if not confirmed to be present in the latest version of the program.

I deleted the thumbnails/ directory as well (not really an "accident", I assumed they would be re-generated, but they didn't). I ran this script to regenerate them manually. (Run this in your outputs_dir directory.)

for name in *.png; do
  echo "Converting $name...";
  convert $name -resize 256x256 thumbnails/`basename $name .png`.webp;
done

Sorry, I haven't installed the latest version, and don't have time to for the foreseeable please close if considered fixed thanks

In Windows the following batch file does the trick:

@echo off
for %%f in (*.png) do (
    magick "%%f" -resize 256x -quality 80 "thumbnails/%%~nf.webp"
)
