I'm looking for a CD or similar pack of royalty free (or maybe even royalty paid) special effects stock photographs and videos/animated images of things such as explosions, flames, etc. I'm mostly looking for pyrotechnic photographs for use as explosion sprites in my games. If you don't know about any of these, do you know how I can obtain such images via other means? I do not have access to a special effects studio, although if you can recommend one in the UK (preferably Scotland) who do contract work, I would appreciate it. Thank you for your help. :)
