Admin Tools (Resize Pictures)
Using the admin tools, you can perform operations based on individual albums (or for all albums in your gallery). The admin tools contain various small tools - most of them being used to control pics in albums.
Available Tools
A collection of utilities to:
Update thumbs and/or resized photos

Use this if you have changed the settings for thumbnail or intermediate images in config, or if you have to replace corrupt versions.
Select the radio button for this action, then choose to rebuild the thumbnails, intermediates, or both.
This uses a lot of server resources, so if you experience timeout issues, try setting it to process smaller batches ( 45 is the current default ).
Filename ⇒ File title
Mass-create file titles based on the file name or the upload date
Delete file titles
Use this to clear the file titles from one or more albums.
Delete original size photos
Use this to save space on your webspace.
When selected, Coppermine checks to see if an intermediate copy exists, and if it does, it deletes the original sized picture, then re-names the intermediate. If no intermediate exists, Coppermine leaves the original in place.
Delete intermediate pictures
This will delete intermediate (normal) pictures.
Use this to free up disk space if you have disabled 'Create intermediate pictures' in config after adding pictures.
Delete files that are older than a set number of days
This will delete files that are older than the number of days you specify (normal, intermediate, thumbnails). Use this feature to free up disk space. Warning: the files you specify will be deleted for good without further warnings!
Delete comments on missing files
Sometimes, when pictures have been deleted, any comments associated with them remain in the database. Use this to remove them from the database entirely.
Delete original image backup (watermark mod)
This will delete the backup image. You will save some disk space but not be able anymore to undo the watermark!!! After that the watermark will be permanent.
Reload file dimensions and size information
Reset view counters
Sets all file view counts to zero in the album specified.
