Hi Everyone,
We have fairly generous file size limits on jpegs, but in the interest of not making the pages so large as to be hard to view, we ask that you try to keep the images not too large in either dimensions or file size. I find that in general an image 800 pixels wide is fine for most things and doesn't clog up the page loading or viewing.

One thing I would like to point out is that we have noticed that the "uploader" tool can be cantankerous in this version of vBulletin. Sometimes it takes a few tries before it uploads, and there is no indication why it didn't the previous time. So don't give up too quickly if you are having a hard time uploading an image.
