I'd like to valuate a new idea.I don't know the server limit but i think is not a problem to ad for every image also a song in a low resolution as we can find on flash site intro(i mean about 200k or 300k of mp3 in a low resolution).No problem with the law couse the limit of 300k it's only a loop of an original song.
Let me know if is a good idea
Thank you for your collaborations
