Hello.

I made a website template in photoshop. It's current dimensions are 800x600 pixels. However, I'd like to also make a 1024x768 version of the template. Is there anyway I can easily resize it instead of remaking the entire template?

Perhaps something with resolution? Right now it's 72 pixels per inch.

Thanks in advance!

you can try changing the image size in image> image size

yes, resizing the image is possible. Make a copy of the document first (if necessary join all layers first and after the copy undo "join layers") and open a new file. Give that file about 300 DPI or more, that way your picture quality will be better. Paste your copy and resize under image -> size.
