Hi Harry07
Are you using Windows software or your camera's own software program?
I've had some experience with "Kodak Easy Share" software and it can be a nightmare!

especially if you try renaming folders and or files, and even moving them within my pictures, you can end up with extra copies.
I have a Fuji camera at the moment and the software is easier to use than the standard "Windows Image Acquisition Transfer Wizard" thing.

You should have an option to chose what program (your camera's?) you use for Image transfer from your camera to the default folder "My Pictures" and my guess is windows will always make some sort of file copy, MRU... also in CCleaner (Advanced) tab do you have (Only delete files in Windows Temp folders older than 48 hours) checked? this may make a difference.
Another way to transfer pics from your camera to a PC
After connecting the camera and turning it on, close any software apps that start' and browse to your camera's pictures storage folder on the camera.
Windows basically see's a camera as a removable drive, select the folder or files and copy them to (by default) "My Pictures" folder, by doing it this way you should have more control over whats going on.
Windows will probably keep some info in a temp folder that CCleaner should clean.
