Hi,
This is what I did:
Phoca gallery - Images - select category - put checks in the small square box beside image - hit delete
Ok, how did you organize your original images? Are all images of all category(s) stored in
/images/phocagallery or have you created subdirectories there? If so, then look with FTP in the directory:
/images/phocagallery/your_directory_were_the_original_images_of_the_deleted_thumbnails_are_stored/thumbs
If this directory is not empty, you see your thumbnails, which should be deleted. (And they still are, but only in the database)
They are for example named like this:
phoca_thumb_l_filename1.jpg
phoca_thumb_l_filename2.jpg
phoca_thumb_m_filename1.jpg
phoca_thumb_m_filename2.jpg
phoca_thumb_s_filename1.jpg
phoca_thumb_s_filename2.jpg
....and so on
delete these thumbnails first, and then the now empty directory
/thumbs itself.
Now go to backend --> Components --> Phoca Gallery --> Phoca Gallery Control Panel --> Phoca Gallery Images
--> Multiple Add
and create the thumbs again.
Kind regards,
Benno
