Is there some kind of add-on or a download that can let you preview .psd files without having to load them each time like you can with jpg's and giff's? Really interested in what you say, it takes forever to load each file in photoshop. There must be an easier way.....
Download irfanview... It supports multiple formats List here http://www.irfanview.com/main_formats.htm
I highly recommend Thumbs Plus from Cerious Software. I've been using it since 1996 and it's the best image viewer I've found.
you can, but you need half-way decent photo managing software to do it. i use ACDSee myself, love it.
