      cntech.atlassian.net had a couple of thumbnail-related OOMEs. This is caused by a smallish png ~3.8MB but with a 26000x24000 dimension. You can easily reproduce the problem by just generating an image with a white background of that dimension.

      convert -size 26000x24000 xc:white oom.png

      Similar to JRA-40084, I think we should reject images above a configurable dimension, causing the image to be marked as thumbnailable=0

      Possible Solutions:

      • Thumber should reject images above a configurable dimension.
