If I look at the stats for my gallery it says I have 68 images, even though I've only uploaded 36. During some searches, I've found images appear twice. If I delete one of those images and then reinstall it with the same tags and description, the galley image stats first decrease by 2 on the deletion and then increase by only 1 when I reupload. Could my database be corrupt - or could I have duplicate images inside my zenphoto directory structure that I need to purge?

Have you tried the "refesh database" button on the admin overview page?

Yes. It does not change the statistics.

What zenphoto version do you use? If it is not 1.2.5 you should update.

Sorry, I was going to add that to my original post but forgot.
I'm using zenphoto version 1.2.5 [4022]

How are you deleting the image?

I've either used the administration tools to delete the image, or I simply move it out of the catalog folder and then move it back using a FTP tool. If I use the latter technique I then reload the main catalog in a separate Firefox tab. Using either method, I then restore the old comments by hand, using cut and paste from a separate text file, and then re-tag the image. Either deletion method seems to give the same effect.

As the number of images in the db are small, if necessary I can simply regenerate all the images and text files, and hope that whatever I did before to cause this problem doesn't happen again. I don't want this to turn into a time sink for anyone, as I may have cause this weird problem merely but uploading the same images more than once or some such error, which I'm unlikely to repeat again now that I've set up a better way to edit my php files offline.

Please intstall the 1.2.6 RC1 and do a database refresh. Let us know if the problem is then solved.

It did not solve the problem, but I'm okay with simply closing this case.

What are you using to look at the stats for your gallery?

The zenphoto admin overview tab and statistics tab.
