EDITING PICTURE SIZE Note: This is important if your camera takes big pictures. You don't want to post pictures that are way too big. People with dial up will get bogged down by big pictures when opening a thread. Before you post the pics make sure they are proper size. Simply click on the picture to look at it first. If it is too large, go to BACK and click the EDIT above the picture button. Under RESIZE PICTURE click the "75% of original" button then click the RESIZE button. Once this is done, click on picture to open it and check out the size. Once they are acceptable, simply copy your Img string over at that point.
