Hi guys! i've got a samsung c100 and when i'm trying to download wallpapers from this site, i got a message not supported or sort of that. can u help me out

Download the image to ur pc, go to paint, save as gif file, upload gif file to download shack and then downoad, it works... i dunno why but my c100 supports only gif images. it says "unsupported content type" to jpeg files.
