Suggestion: Add feature “Only Add Missing”

Can you please add a way to tell the plugin to only regenerate missing thumbnails??? I’m thinking a checkbox option.

Also, add another checkbox to remove undesired sizes.

The intent is to limit the processing that is done and to reduce execution time for tasks that don’t require regeneration of all images, and/or to split the task into smaller jobs.

I have a site with over 100,000 product images and need as many as 15 thumbnails of each. I’ve been having problems with the plugin failing to finish, either due to timeouts, running out of disk space and other factors. Each time this happens, I have to start “regenerate” over. Each run takes over 12 hours to execute. This is very impractical and problematic because the plugin appears to be reprocessing existing files.

These changes would allow me to restart incomplete regenerations when changing the required image sizes.

thanks.
