So the photoshop organizer is an online website, or on your hard drive? Or both?
I haven't used it, so not much help on that part...

General photo stuff - I'm not an expert though...
I have my computer set to add all new pictures to My Pictures in the Documents area of Win XP.
I make folders there with appropriate names - family, art, scenery, misc, etc

Most of the photo programs I have used will use those same files by "seeing" them. If you make editing changes you would use "save as" or "save" to save any changes made.
to keep the original photo as well as the changed photo use "save as" and change the name that the new edited one will be saved under {I add a letter or number on the end- so i know it's the edited one}

If uploading to a website - that usually just places a copy of your photo onto the site.
Your original will still be on your computer.
