First of all - love this addon, great work!
But I have a few problems with it.
I have loaded all the images into my shop, they are displaying fine, and in admin side they are shown when selecting product:

but after some manipulation (either thumbnail cleanup or something) they are not shown in admins edit panel:

If I add new images, the old one is just not used anymore and is not displayed. Although I have no idea why - some of the old images are displayed correctly.
Second problem is opi_thumbnails.php is not reacting to any changes in configuration. I change this and that, but the thumbnails and the main images stay the same. Could this have to do with file permissions and opi_thumbnails not beeing able to overwrite old files? Is there a way to enable logging, so I can see what opi thumbnails did and where were the errors?
And the last problem - is it possible to make this plugin take the information from current database entry images, re-do the image and save the new image as well as new database input?
I am asking because I add my information with EasyPopulate through CSV file and I would love to state that image field is 1.jpg and then tell OPI - do the magic! and it would rewrite all files automatically? Otherwise there is a lot of manual click-click-click work involved.
