I'm sort of a beginner to photo editing and was wondering when I use the option to flatten layers or items in Photoshop or Snag-It will the final image size be smaller when I save it, or does it not make any difference at all? I'm trying to reduce my images as much as possible without losing any noticeable image quality.

Here's a nice way to see much larger pictures on Google, when doing a regular search that turns up pictures, and when searching Google Images, by hovering your mouse cursor over any image thumbnail.

• First, you need Firefox (FF)
• Next, you need the GreaseMonkey extension for FF.
• And finally, you need to go to Userscripts.org and install this script.
