    I can't see what you are aiming at as your image has gone, but there are also Decal Nodes which project an image on a figure (but do not spill over the surrounding scene). They aren't lights, though.

    There's a tutorial here, and a discussion here.

    Ditto on not knowing precisely what you're looking for now that the image is gone. But I second the suggestion to look at this product:

    If you don't want to buy something t to solve the issue, I think the vendor has been active in the forums discussing this product, and you can read the posts to see how it's done. Generally, any hard-edged light (distant, point spot) shining through a geometry with a transluceny image, will project that image into the scene. The idea is simple, but getting it to work right isn't always easy. The aforementioned product makes short work of it.

    Before you go spending any money(especially what they're asking for that product), I would encourage you to go ahead and try Tobor's idea.  Make sure you use a point light to get the sharpest image, then create a plane and apply whatever image you want to the cutout opacity.  Just think of a projector bulb shining through a layer of film onto a screen.  Yes, it will take some work to get it right, but that's half the fun in my opinion. I probably spend about 5% of my time creating decent quality images and the rest just experimenting and trying different stuff.

    Just out of curiosity, why a point light, specifically?  I would think that a spotlight would be more suitable for something like this.

    Or, am I just counter-intuiting the crap out of everything, like I always do?

    Here point light means the type of emitter, an infinitely small point, versus the Point light fixure that D|S gives you. Both Spot and Point lights can be changed from point to an area; with either, the larger the area, the softer the light.

    Either one would work, and in fact, Point lights (with emitter set as point) have an advantage because they can use IES profiles, which can further shape the beam. The Spot light fixture does not have this option.
