Try downloading irfanview from
www.irfaniew.com. It is an excellent FREE application that will let you resize your photo. It is very easy to use. Try resizing it to 640X480. I suggest you resize it, then upload it to the same directory with the same name so that everyone who looks at this page does not have to load that enormous photo of your truck.
I use SmartFTP or, for quick uploads, Internet Explorer. It is already on every indows computer, and does the job just fine.
WS FTP works well, but has one of the least intuitive interfaces I have ever seen. I started out with it years ago, and replaced it ASAP!
