Making better looking thumbs and doing them in batches.

I should note with this that I am not recommending Photoshop to batch process thumbs but for those that don't have other programs this is a good way to do it. The most important part of this tip to most webmasters here will be the simple step that makes thumbs jump out and be much more clear looking and that is a step you can save into a batch by itself.
