Set of Kings with a 3 Flush Flop

My table image:
I had folded most everything at the table except for checked big blinds, and completed a few small blinds. I had been playing tight, but not sure if anyone noticed for the 20-30 hands. I hadn't made a pre-flop raise yet.

My read on the table:
Everyone at the table was loose. They would play anything to a flop, so I was waiting for a chance like this. I bet hard (the pot) on the flop to see where I was at, and I was ready to fold to a raise if I was put all in. I had pegged the villian on a flush draw because he took a long time to call on the flop.

Comments? What do you think this guy has? And would anyone play it different? (Will post the River after any discussion)

the pot is around $6 and you have around $6 left - push. If he has the flush you still have 10 outs to a full house.

That is exactly what I did... I felt I had to go all in to give him the incorrect pot odds to call. Thanks for the feed back.
