Topic: round edges for images

greetings,

i want to use simpleviewerpro on a website with white background and i need for the design round edges for the big image.

the pictures are all from the same size (simple viewer will have a fix layout), but they will be replaced from time to time by somebody else. of course its possible just to add the white-round-edges in  photoshop and then upload it, but for maintaince in the future thats not really a solution.

my first idea was to put a layer with the 4 edges over the viewer - but i don´t really know where to place it in the .fla file ?

my second idea was to put by actionscript 4 grafix on fix positions ... but here i also don´t really know where ...

i´m more programmer than flasher, so please help :-)

thx
