Saving a File to disk in a .swf

I would like to be able to let users save something they have created by dragging virtual furniture into an isometric grid which serves as an apartment floor. I do not know how they could submit their pictures without just pressing print screen.

Is there any alternative to print screen?

Clicky

I want to be able to make it do what the tilemachine does by saving the tile to disk, but with the grid and furniture.

Thanks
