Loading Sprites

Is there an easy way to not load a sprite from the computer's memory each time I want to use a sprite? I suppose I could load one, use HideEntity on it, and then use CopyEntity for all of the others.

What do you guys do?

Just hide it if you don't need it at this time. Depending on how many sprites you will need that is :o)

I only load stuff at the start of the level/game. Any additional instances are just copied using either copyentity/copymesh depending upon what it is. Best not to run commands beginning with 'load' in them during the actual 'game'.
