First off..... Gateway... really??? Why? lol... no offense... but they are pretty much known as junk in the IT industry (sorry... no offense meant)
Secondly.... you don't have to change the name of anything. When you upload pictures you should be able to choose where they go.
I advise people to NEVER use the folders under documents & settings\user login. Why? Because if your login profile gets corrupt and you try to repair it with the windows tools it more often then not wipes out all your files.
Personally I believe everyone should have a SINGLE folder directly under the root of C:\. It can be named anything.... I do use my name but you don't have to. The idea is that you have ONE MASTER folder and you create subfolders under that master folder, i.e., C:\MASTER\PICTURES, c:\MASTER\MUSIC.... etc. etc. You save ALL your files somewhere in that directory structure. This makes backing up your data EASY because you simply back up the MASTER and include subfolders.... instead of trying to find files stored all over the place for backup.
Software should be installed in the appropriate directory (usually under Program Files) and not backed up. Why? Because it's a waste of disk space to back up programs that you can easily re-install if something goes bad (as long as you have the software). Really you need to only be concerned with backing up your files.
Hope that helps
