Stage Size problem

Dear forumer,
I was planning to make a photo gallery using AS3, i have created a new .fla file and set my stage to 465x200, and load in photo horizontally, with the stage size 465x200, it enable user to see oni 3 display thumbnails even if u maximize the debugger window.

then inside my code, i add a rect sprite that’s 1024*768, i press on ctrl + enter, the default debug window is in the size of 465x200 since i set the stage that way, but when i maximize it, i saw more than 3 thumbnails, and i trace my stage width, it’s now 1024x768.

is there anyway that i add a large sprite on a small stage but my stage still remain small?

I want my user to view oni 3 thumbs when i maximize my debug window, how can i do it?
