Garbage collection, Memory usage issue

Ello ello…after hours of confusion I am having trouble with garbage collecton, I hit 1gig easy. I don’t have the code on this machine so basically its a gallery database that the user changes and views images enters details for each item etc etc (100’s of images and mc’s withing mc’s within mc’s)

Even unloading/removing all events/listeners the memory still creeps high although I have found when I load a single image (jpeg) then unload it the memory drops from 1 gig to 100mb again. So Is this unloading of an image triggering garbage collection to run? It seems so but not 100% sure.

<question>
Is it possible to kick start GC or am I already doing that via unloading one image to trigger it. Or can anyone try kickstarting GC by doing as I have to confirm.
</question>
