Slow forum load. Export images on other server???

[ar2]

Lately my server stopped cooperating with me and started to lag.

Is there any fast way to split images from main server to external server? Maybe some kind of rewrite like this?:

adress.com/forum/image.gif
for
img.adress.com/forum/image.gif

yea but you will have to place the link to the new images on every image. basicly just add the full URL to the image for each picture (ex. http://imagedirectory.com/mytheme/images.gif)

That's why I'm asking, is there any way to add automatic hack to do it for me.
