i'm having some trouble trying to make a pdf out of several pages of jpegs. i'm a bit new to macs, only owned this macbook for a couple of months, but i'm aware that mac os x has a pdf maker built in. i tried the compiler and apparently, all it made was several pdf's, with the same file names as the original jpegs. what program do i use to compile jpegs into a single pdf and how do i do it? thanks!!!
