Image Handler 5 (for v1.5.5 - v1.5.8) Support Thread

[NWCE]

I have upgraded my store to Zen Cart v.2.1.0 and am using IH 5.3.5 with pHp v8.3 on my server

Due to a very large image folder, I didn't upload that folder during testing....and now that I'm live and the site is using that folder, I have one weird problem. My additional images are all showing as Large images, not thumbnails with the ability to enlarge them and these additional images are duplicated (showing 2 of them instead of one).

I have tried uninstalling the plugin via Admin->Tools->IH->Uninstall and then reinstalling. I received the confirmation of IH install at the top of my Admin panel when logging into my admin and I then went in to Admin->Images and set the Let IH resize images to true.

When going into the IH in Admin-> Tools, everything is there and working, and there are no Debug Log errors.

Can anyone point me in the right direction on what I've done wrong??

Thanks!
