ghost thumbnails

[Nathalie]

I deleted pictures but thumbnails are still there somehow:
http://www.manypixels.eu/index.php?x=browse&category=

Those 12 pictures are not in the folders /images or /thumbnails anymore, but it looks like there are still some references to them.

What can I do?
Thanks,
Nathalie

I re-uploaded one by one the ghost pictures.
Any way I could have cleaned the data?

Which data? To make new thumbs you can use thumb regenerator addon.
