Hey, nice site etc…
Now, I can’t get any of your gifs to animate on my end through firefox or IE, so I’m assuming they are animated on your end? The only thing i can think of is that frontpage did you a disservice by resizing your pics and messing them up. I also might say, every one of those is a link, it just links to the same image you clicked on. It works, but there is really no point of linking if its the same pic. So check if frontpage is doing something wierd… or, just re-upload some and overwrite the ones frontpage created.
As for a better creator? Everone rags on frontpage (I do aswell) but its really not that bad for learning about everthing first. It used to create horrible code, but its gotten much better. Dreamweaver is considered a “better” editor, but its true that in the end, you will want to get towards coding yourself. (And not making every page by hand, learning how to create galleries, etc)
Oh, and yes, you can use notepad, but a better solution is something that helps you by checking your code and adding snipits as you go. Check out a program called emacs. It works on any platform.
Best of luck.
