Help Please

[babydoll]

I am new to making sigs....I can get the name in perfect(hexed and all), but when I add pictures to the background, I cannot fad it all in to get rid of the lines so that it all looks like one picture and that you cannot tell what I have added and what I have not....The other problem I have had is, I have messed around with the font size and colors...but I cannot get it to be a solid letter, it always comes out kind of like balloon letters...What am I doing wrong with that? Someone please help me with this if you can....Thank you!
