image gallery navigation

[spyder]

i have what i believe is a relatively easy problem, i just dont know anything about javascript.

i have several images on a webpage all set to hidden except one. they all have unique id's. i would like to have 2 links. one will show the "next" image (make one image visible and the other hidden numerically) ad the other will show the previous image.

thank you very much. also if you have suggestions or anything i would greatly appreciate it.

is there any way to modify this script so that is takes up teh whole browser?
