Long time no journal! How's folks been going in here?

To cut to the chase I had a dumb idea whilst watching the gameshow 'catchphrase' if anyone is familiar with that in the UK, and wanna see if it's a way I can set up a giveaway/free commission and all that.
The nutshell is in any scrappy picture that's bracketed with '(Guess the phrase) or GTP in the title or description, whether on twitter or on FA here, the first person the comment will be poked in a reply for a free basic image, probably a post-inanimate TF thing or whatever might be related to the topic of the picture,
When I do them might be random and there will be some unfair elements like timezones or having to know the name of a character in the picture (which will be in the description probably)

One rule will be only one answer from a person will be allowed per 5 minutes, and answers from people between them will be hidden if I catch it, and only one guess is allowed per comment.

Folks reckon it's worth a shot or too gimmicky?
