What are the limits for MySpace Emoticons?

At the time of writing, MySpace Emoticons have the following limitations:

• Emoticons are limited to a maximum dimension (height and width) of 50x50 pixels
• Emoticons are limited to a maximum file size of 200 KB
• Emoticons can be added from the following file types: BMP, JPEG, GIF, TIFF, PNG and ICO
• You can add animated emoticons (GIF format)

You do not need to worry much about the dimensions of the file as MySpace IM will automatically resize it to the maximum when you add the emoticon.
