Hi,
There are several other members reporting some very odd manipulations/deletions of images, etc. on their Auctiva accounts and active listings. I recommended they change their logon passwords to both Auctiva and eBay and make them different passwords to see if the problem stops. I would honestly do that as a precaution. If that suddenly stops the problems, let Auctiva know by opening a Support Case.
Have you recently run any spyware and antivirus scans of your computer? If not, I would before you change the passwords.
