This could be specific to macOS, I guess.  The way to debug it is to
step through the code which parses and displays the image, I suppose.

Anyway, can you describe what you see when you try to open one of
those images from within a ZIP file?  You said empty buffer, but
that's not how Emacs displays images it cannot draw as images.  So
maybe you didn't describe the display in all the detail?
