If anyone is having difficulty still with resizing your pictures I would suggest using Irfanview. I use it constantly and it's so easy. All you have to do is go to
www.irfanview.com and click on the download button and download it. Then once it's set up all you have to do is open your picture and click on the Image tab at the top and scroll down to Resize/Resample. Then you can choose any size you want. After you have the size you like, click save and then you can upload the photo into your photobucket account and you will have the size already set. It's a lot easier! Good luck!
