Opencart - solution to the problem with tightening the picture of the product

There is OpenCart 3.0.2.0 (trs-3.0.2.0)

There is a problem that:
1. When uploading an image to the product card - the image is sometimes not pulled up.
2. The main problem is the hodgepodge of images. Previews, internal images - do not correspond to the admin panel.

These issues need to be addressed.
