I've got an issue with this plugin. When the cache of this plugin contains a lot of images the adminsitrator gets very slow due to the plugin checking cache images on saving / interacting with the database.

Is it possible to change this behaviour so the script stops checking cache images when administrating?

I'm not saying it utilizes the database. It just runs a script and checks every single cache picture which makes the site extremely slow. This happens when you save or delete. So when the cache contains more than, lets say 150.000 pictures it first checks if every one of those 150.000 pictures  exist before actually saving. Maybe it runs this script on the onUpdate/onSave method or something. Also im actually using the Pro version.
