Simple loading .... cant find anywhere

hi! im new to using flash … and of course, fin it very interesting …

i have been searching for a very simple loading sequence for an image on a flash presentation … but i can find one … on my website, i have an image and basically, using flash, just broke up that image to make buttons out of various section to connect to different websites etc … but it takes a while to appear on the site, for about two seconds, i see a white screen and then my image appears

i’d really appreciate it if someone can give me a nice link or two, or provide me with some code to understand this concept or having a “preloader” and of course, using a preloader for this image so that a white screen doesnt appear for a while before the image shows up …

i just have one frame on my flash presentation, and that one frame has this image which is divided into sections and each section is a button … (just background info …)

thanx
