Is there a standard for Album Art?

Is there a standard for Album Art? I using a couple of methods to assign the artwork to my music files. The source images ranges from really small ones e.g. 100px X 100px to bigger ones like 500px (all jpegs). Somehow, they don't always appear (e.g. on my walkman phone or my wife's ipod), but they do appear on my PC media player.

"I would say it depends. The images iTunes downloads are all consistent, but linux players like Amarok look for Album art from Amazon - it basically does a keyword search and whatever images it can find it makes available as album art choices. Those images are all sorts of sizes and formats.

As far as players, some older players had a resolution of 176x132 pixels versus the newer 320x240. The iPod touch has 480x320."

80x80 pixels, plain and simple.
