Load an external MC in a contenitor mc from a dynamic text link?

Hy guys,

i’ve a similar problem of sintax321 that i’m not able to solve…

I need to create a dynamic portfolio.
I have an external text file that contains links to the sites. I want to load an external image (or swf) in a contenitor mc anytime someone clicks (or even better on rollover) on a site name.
I make it simple (sorry for my english):
How can i target “site1.jpeg” (or swf) to “cont_mc” by clicking (or rollover) on a external text link?
I’m in trouble…

Thanks in advance for you help.
