I'm working on a favicon which needs to have multiple sizes.
Right now, I have a PSD file for each size, e.g.,
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.
