4.15. Attached picture
This frame contains a picture directly related to the audio file. Image format is preferably "PNG" or "JPG". Since JPG has the best lossy compression and PNG the best lossless compression and both are free I don't see much room for other formats. I didn't want to forbid other formats though, since there might pop up better ones in the future. Some people will probably think it is neat with ICO pictures as well. Description is a short description of the picture, represented as a terminated textstring. The description has a maximum length of 64 characters, but may be empty. There may be several pictures attached to one file, each in their individual "PIC" frame, but only one with the same content descriptor. There may only be one picture with the picture type declared as picture type $01 and $02 respectively. There is a possibility to put only a link to the image file by using the 'image format' "-->" and having a complete URL instead of picture data. The use of linked files should however be used restrictively since there is the risk of separation of files.
