2 months ago, I bought a paid Photobucket account that has now expired, and suddenly all my pictures look like they've been saved in low quality.
See the difference:
I didn't have this problem before I bought a paid account. So basically I'm being "punished" for actually giving Photobucket money in the first place, as everything would've stayed the same if I hadn't.
It seems okay again when I upload new pictures, but I don't have every icon saved on my computer so now there'll be low-quality icons where there were pretty ones before:(
