Hi FranBrad! Welcome to the greatest gardening forum on the net! There are some free websites you can upload your pictures to. One of the more popular ones that comes to mind is photobucket.com. Once you upload your picture, come here to post, and there will be a button down below that says "URL" (you may have to hit 'full reply form' first, if you don't see the URL button). When you hit 'URL', you'll be able to paste the address of your picture so that we can have a look see!
I'm kind of new to gardening, but someone may be along that can id your disease/critter problem without a pic. It's much easier with a pic though
