I'm using 1.3.8a

My question involved customization of images in photoshop.

I am well versed in photoshop, not an expert but I can get the effects that I desire.

The template I bought, came with PSD files. One of those files is the entire webpage in one file. I found this to be the best for me to customize as I was able to see the entire webpage in one go.

Am I able to customize the zencart in this manner ?

Or am I supposed to find each individual image and replace it with the graphics I want.

I would prefer to just customize the one large psd file and then just save or chop them up some how into the specific files . Anyone know how this is done ? or could point me to a tuitorial.

Any help or comments would be much appreciated.

thanks
