How can I replace the standard 'script' icons on my toolbar to small images to illustrate them. (I have the small png images just need to know how to apply them)

For Vegas Pro 8, you need a 16x16 png but it must include an alpha channel. Name it the same as the script except using the PNG extension.

Can you give more specifics?

Ah! right Ed. Many Thanks.
I hadnt included .dll in the file name. Now they work.
