I needed something to add interest to an otherwise dull laundry area, but vintage image tin signs are somewhat hard to find and can be expensive. I made mine out of spare photo frame and an image I found on the net, but you can use post cards, magazines, cd album covers etc
Search for an image you like on Google.
Make sure it is a decent resolution so it doesn't pixelate (if it needs to be enlarged). Save it.
Either manipulate to the size you want in word (import picture) or photoshop, or print it out as it is.
Pry open the back of your frame. Carefully trim the picture to fit if necessary. Put the image in and put the back of the frame back on. Well done!
