I got these specs from a client, who wants the following string implemented as a button behaviour (I'm producing banners):

INCLUDEPICTURE "http://eur.a1.yimg.com/eur.yimg.com/a/eu/any/adscenter/pixelshim.gif" \* MERGEFORMATINET INCLUDEPICTURE "http://eur.a1.yimg.com/eur.yimg.com/a/eu/any/adspecs/flashmxconvert.gif" \* MERGEFORMATINET

Although a work with Flash alot, I've never used behaviours before. And from what I see, there's nowhere I can paste this string - all I get is an option to choose an event (which is not mentioned in the specs/instructions i received), and a number of Actions (none of them seems to apply).

I searched this forum, as well as Adobe's, but haven't found anything helpful so far (and I'm getting quite annoyed in the process...) - anybody can give me a pointer in the right direction?

Thanks alot!
