I have the following code. My program loads 20 pictures in one panel and each pictures has for the moment like 500 Kb, but in the future they shall have like 2~6 Mb.
When I use this part of code, my program that uses only 6 Mb of memory, but jumpes at 202 Mb when pics are loaded. I need a method to resize or make them thumbnail or something to reduce the memory.

I don't know for the moment how to use the System.Threading, but I want to know if it shall help my program, if not, then help me replace parts of my code.

Regards, Cosmin.

Or at least help me find a way to load the pictures without loading the memory(RAM) as it does now.

Thanks

Thanks m8. I did it thanks to you and it burns up just 30 Mb with my pictures (20 of them).
