For images I would use a cost estimate of width * height * 4 (this is typically what the memory cost to decompress and display an optimized PNG). For audio this is more difficult as it is unlikely that the entire file will be loaded into memory, or even that a significant amount of it will be loaded into memory unless it is playing (in which case you do not want to unload it).
