If you just need static luminosity/illumination from a texture image you can add the diffuse map (whether the default of the screen if it's separate or selectable, as @inversekinematics suggested, or one of your choice or construction) to the Emission Color channel of the surface, change color to white, and crank up the Luminance until it's what you want.
For animated textures, there are mCasual's MatAnim script (free):
