I always had the same amount of images… As well, my traffic did not increase that much to increase server load that much.
I have had those validation errors for the last few months now but that did not affect my server load at all. Plus the images are all hosted via TinyPic so it should not affect it all that much.
As i said its just simple modifications that were done. Aren’t the images affecting bandwidth and not server load?
