When I click "More Images" on a release or artist, the first image pops up ok. The issue occurs when I switch images: when I click the 'Next Image' button ( >) or the right arrow key, the current image momentarily resizes to the height of the next image, and then the next image is displayed. I find this very annoying and distracting. It would be great if didn't happen.
Here is a slowed-down screen capture to show you what I mean.
