I'm trying to make an image texture that glows in Blender. An example might be a television or a smart phone. How can I accomplish this? Any help is greatly appreciated.
I haven't rendered the image, but this seems to do the effect that I wanted:
Add a plane, unwrap it and give it an image texture. Set the nodes as pictured below (connect the Image Texture node to Emission node). Set up the emitter's strenght.
If you want to increase the glowing effect you may do this in Compositor. Just add a Glare node and experiment with its settings.
Set your image texture, and set your material type to "emission".
edit if you're using cycles:
