Hi,
I am using latest OSClass with Zeta theme and when I upload images they look very bad on my website, resolution or image generation is very, tried with GD and also with ImageMagick and the result is the same. Any known fix for this?
Here is an example: https://prnt.sc/uYASSaYKR4zj

Check your media settings if your image dimensions are large enough.
Also try to switch to ImageMagick.

Once you do it, you will need to publish a new listing to test results.

I already switched to ImageMagick. How large should the images be in order to get a good quality?

At least 1024x768px

For the images on listing page or for all 3 options?

If you install osclass, you have sufficient image dimensions here.
