Short answer: No, I don’t think so.
Do you mean when you have an image open, separately in it’s own pane?
There is a keyboard shortcut to zoom the entire text and interface. On MacOS it is Cmd+= and Cmd± to zoom out. In Windows I guess it is Ctrl+= and Ctrl±
And Cmd-0 (zero) to go back to actual size.
That zooms everything, but it also zooms the image. Other than that, I don’t think there is any way to zoom just the image.
I don’t know if ctrl-scrolling does the same thing. That doesn’t work for me. I can pinch-zoom with my trackpad, but that only zooms the text size. It does not scale the interface or the images in a separate pane.
