What is the maximum size we can use in Attach Image?

Hi Everyone,
I am trying to use Attach Image Type in my custom field.

But, I noticed that due to some size constraint, it doesn’t show me the picture whereas for few picture, I can easily see the image shown.

Just wanted to check, is there any constraint on viewing specific images with size and type. I mean is there any constraint that specific type/size of image can only be seen in Attach Image Type?

for the size I think there is none, I have attached pictures which resolutions bigger than my screen 14". But maybe there are constraints for the type

Are you self-hosting or using SaaS? There can be size limits, set by web server.
