After installing Renderereditor run HIR, then you'll have a few new objects in Add\Items\[M]objects category if I remember correctly. Their names starts with "joan646" or something like that. When you adding one of this items, you can select a .png texture in Renderer editor - you should move it to the textures folder (in the renderereditor folder). Then move your item around to set the projection place, it's just like the flashlight projecting the light, but this time you projecting a texture. Different items are using different projection method, similar to Photoshop, the best is probably "multiply"
