Regarding resizing pictures...I had same issue and I'm no computer whiz...what I did was from the "my picture file" on my pc where I had the item photo selected...on the left hand side of my page there were options...if you select
"e-mail photo" it will most likely ask you if you want to re-size photo(it will make the file smaller). I e-mailed the photo to myself, then saved it in my picture file , renamed the photo. Then you can select browse from the OldGobbler website and pick up the new, smaller file photo. There is probably a lot more scientific way to do this but that worked for me.
