The thing about the pics is Photo Gallery is for corn pics all other go in gen chit chat. By the way I liked you set-ups. You can post pics of anything in gen chit chat, other animals, kids, family, wedding pics....
As for sig you should be able to fit everything you had by making a list (not hitting return), look at other sigs you'll see how much will fit on a line.
To resize you need a photo editing program, one probably came with your camera. I resize mine to 800x600, then I can do the five pics per thread no problem. You also have a lot of flash, making it hard to see your pics. good luck and welcome again, susan
