I like update my photo gallery from 1.4.25 to 1.5.12 but have problem with this message:
Coppermine critical error:
The group table does not contain the Anonymous group !

I'm added table Anonymous into usergoups but exist eguale error or message. How to solve this problem?

We already discussed that in 2 threads in the last time. You can either perform the changes of the upgrade process manually. Better, you'd give us more details, so we can fix that error.

Your original image files should be the same in your albums directory.

Try Files >> Admin Tools >> Update thumbs and/or resized photos.

Backups are always recommended before doing any major changes.

Backups also should be done on a regular schedule.

Thank You - solved.
