Tater, open the picture on your computer, then resize it to the size you would like it to appear, save it again (under a different file name if you want to keep the original). Then post the link or upload it again using the smaller picture. Is this the same picture that Grayson uploaded for you on the other site? If it is then he will have to resize the picture for you.
