I just installed Adobe Photoshop 7.0 and I'm having a hard time adjusting to it. As you can see is the background they have three four different pictures in the same layer and the three biggest ones fit like a "puzzle". I want to learn how to do that. I tried the "freeform pen tool" but I must be doing something wrong because it keeps cutting off parts of the pictures that I don't want to get cut off. I don't even know how to make the pictures visibility "ghosted" so that it can look like the one in that website. Can you please help me ASAP? Thank you in advance!
