Taller covers cause gallery background to leave larger whitespace on the row above it

[joonaspaakko]

The cover image on the right is fit inside the square, which leaves some whitespace on the sides and would of course look a bit weird in the animated background. Not as weird as how it looks now, but still... So I should probably fill the square in the background, which will cut off a little bit, but that should still be the best option.
