Do you have that very special photo and you wanted to make it even more special? Why not use this to show the people just how special this photo is by adding led to light it up?

Use a simple 10mm width led strips or any kinds of led that you're comfortable working with. Channel for wire to hide them are there if you want to make this a clean one. 

Diffuser is included as well so you won't be blinded by your own creation. You can ignore the diffuser if you want it to stand out further.

Diffuser should be printed in white, or any colour you prefer to add some mood to your photo.

if this thing is too small for your led strip, just stretch it by its width, scaling must be the same on both objects.
