Multiple Canvas Sizes in one PSD (Photoshop)

Question

I'm working on a favicon which needs to have multiple sizes.

Right now, I have a PSD file for each size, e.g., 16x16.psd, 24x24.psd, ..., 64x64.psd. After I'm done drawing them, I export each size and combine them into the ICO file format.

What I'm wondering is whether Photoshop (CS5 in my case) will allow me to consolidate all of these files with different canvas sizes into one PSD.

I suspect that I can't do this directly, so I would appreciate any advice as to how to best manage files when implementing something like a favicon; i.e., something that doesn't necessarily downscale well automatically.

Answer 1

I guess you are right you cant do this directly, what you have to do is make a PSD which have bigger dimension such as 100x100 and put all your icons in that particular psd, make separate group folders of your icons like for 16x16 and 24x24 when you need to work on 16x16 just slice them and use it. by this all your icon will enjoy together in a single PSD :P
