do u have photoshop?
if so, try making a sig, and i'll tell u a way to improve it... eventually it'll be a good sig....
make it 450x150 (pixels) and use these pics:
background: http://www.costruzioni.net/images/new%20york.jpg
pic: http://wmg.jp/artist/fabolous/images/565-large.jpg

should be easy enough... no cutting involved...
play around wit stuff, then save a jpg copy DO NOT MERGE OR DELETE THE ORIGINAL PSD... upload it wit imagetitan and post it here...
