Windows are not just for looking outside anymore. When used as picture frames, salvage and store-bought windows are large enough to accommodate poster-size photo or art prints, or a series of single prints. You can keep the glass in, or there may not be any to begin with. Below are examples of how window frames can be used for framing photo prints:

Above, my son and daughter in law's wedding in Washington, D.C. framed by a old window I found in the dairy barn. Below, I've included the Photoshop tutorial for the soft-focus effect in this photograph:
Open photo in Photoshop and crop to the desired size.
Add a Curves adjustment layer (click the little half-black, half-white circle at the bottom of the layers palette) and move up the left side of the diagonal line until you get a soft effect (takes out color)
You can add brightness or highlights by adding another point toward the top right corner. Click OK.
Add a Color Balance adjustment layer and adjust the sliders until you are satisfied with the colors.
The final product, a nice soft romantic effect.
