Now that you explained things in more detail this sounds reasonable to me.
And it probably wouldn't be much more expensive than it is now as checksums
for new images are calculated anyway (per default they'll be added to the
image-list but not to the ignore-list).

Some time ago i used a album-creation tool that stored created thumbnails in
a subdirectory of my image-db. I once added all of those images to the
ignore-list which resulted in a huge ignorelist (I probably still have
those images in the list, even if they do not exist anymore... I should
Anyway, this was not good practice (I think) but others might do similar
things resulting in big ignore lists.
