So lets see...

If I give someone "props" for doing a cool work of "art" it's different than giving them props to include IN their art. Unless of course the subject of their art is props in which case I'd be giving them props for their use of props in art about props.
Which is not at ALL to be confused with a easel...which is a prop for art, really.
Then again if I think about it from a application contextual standpoint...a poser piece might use a figure as a prop, or prop a figure in the background and include it in the art. I'm not sure I'd give props for that unless it was good art...or a good prop.
But of course the props ARE models after all, unless they are figures in poser in which case they're...figures...
But if I made a model of a propellar, prop, and propped it in a corner against a wax figure of a pilot, named ART...another prop...and it was GOOD art...would I prop it on an easel? And if I did would I get props for that or just huggles and kisses?
I think I need a rule set...
So I guess my rule of thumb will be something like this:

1. Always give props for good art
2. Sell props whenever possible
3. Make art about props wherever feasible
4. When using a figure as a prop in a poser context never name him Art...that would confuse the whole deal.
5. Whenever presented with the opportunity of propping up a beautiful model...take it....friends WILL give you props for that.
6. But don't take picutres...that would be art about props and models' figrues...that would be bad
7. Unless you could sell it as art about models' figures and props and prop it on a easel...for money...that would be good

'kay...I think I got it now.
