I don't know about anyone else, but I have found problems with uploading pics from my hard drive thinking that I have them sized down when actually I really still had a large sized pic.
On the reccommendation of a friend of mine, I downloaded IrfanView. This program is really good for those who are looking to resize pics to a smaller size and them not look distorted. It can be used on most images, gifs and jpgs and other image formats.
Plus, it's FREE

I think the V3.85 also has all the plugins as well. If it doesn't though, the plugins are also free. I know I use it resize all my pics and various types of images that I have on my computer. The program was definitely worth downloading. I have got a ton of use out of it since I downloaded it.
