Does the the info immediately to the left of this screen ("Posting Images in the Stovebolt Forums" with the image of the blue GMC truck not explain it adequately? We have tried our best to explain the process simply.
There is absolutely no reason on Earth why most of the images we are talking about here need to be posted at sizes that exceed 1 meg. Shoot, 500 K should be more than sufficient. I have yet to hear a compelling argument for why I should have to ask others (or pay myself -- which usually happens ...) to pay for bandwidth allowing everyone to willy nilly throw images (not all of which are interesting or helpful ...) around at unlimited sizes.
You are right -- Everything is better which pictures. So learn how to do it.
