You can't directly apply effects to the img elements anymore. The css filter property is blocked by the Neopets validation code, and because it's woefully outdated, that same validation code blocks modern css alternatives because they're unrecognized. Using position: absolute and moving elements around can get messy, and I'm not sure if that's allowed anymore because of the rampancy of its misuse back in the day.
