Optimize Memory Usage

Hi,

I have a program that works whith images (show, make some effects, etc). This program have a icon on the task bar, and on duble click I show the form.
I notice that sometimes my program is using large memory (20,30,40... mb), and when I maximize, and them minimize the memory is refreshed (i think) and the memory used passes to 1mb.

There is any way of clearing any un-used memory ...

Thanks,
