Question:
Due to a slight ongoing problem atm, I am a bit nervous over my use of gas guns on the rape. If a horse rider falls off a horse passing within hearing shot of a gas gun going off, am I liable? So I have decided that I ought to put out notices on the bridleways warning of sudden noise. BUT, rather than just print off a warning I wanted to put a picture of an explosion etc on the notice to make damn sure that it is noticed and the suing b's cant claim otherwise. Any ideas where I can get a picture that I can copy and whilst I am on I looked for a fire extinguisher sign, and went onto HSE site. Nothing there any ideas please greatfully accepted.

Answer: What an astonishing surprise! I have an old copy of Corel Draw somewhere, bought cheap at a computer fair, and various clip art given away with computer magazines. They tend to be US-biased, but this general sort of warning/information symbol is commonly included. The local computer fairs have become very hardware-centred. There are better ones in Yorkshire run by "Northern Computer Markets", but that sort of cheap old-version software seems less common.
