I tried the swf background and the loading bar basically fills but stops there. It doesn't bring up the gallery for some reason. This is the location of the background swf that I created:
http://con-trast.com/upload/back-test.swf
The only way I know how to make a transparent swf is with html properties, so I assume I would see a bright green background even if it worked anyways.
My coordinates and dimensions are exact so I tried resizing my movie clip a couple times and the stretching still occurs.
*EDIT*
Ok so I just gave up on integrating it. I tried a couple other things that helped, but just couldn't get it to work exactly like I wanted. So I decided to just make it a separate page. It's unfortunate but it still looks nice. The only question I can think of now is how do you organize the order in which your images display? I thought it was determined by the order you upload them, but I'm noticing it isn't It's not alphabetized either. Thanks.
