plug ins and all

Im new to this mac thing.
In some sites I ant open ether picture or some sort of flash or what ever. But I cant figure out what is it im missing.
Is there a tool that I can install that can tell me what Im missing, so I can find it and install it?

Thanks

What web browser are you using? Anyway, in order for you to play flash movie in web, you need to have adobe flash player. You can download it from Adobe. Also, for picture, check the preferences to see if you have block the pictures from unsecure website.

Help!

Im new to the mac thing too and am having the same "missing plug in" problem.....I checked my preferences and cannot find the "block pictures from insecure website" box you're talking about - ideas? All I know, is I cannot view brochures, catalogues and often pics.....I have installed adobe flash.....still no luck. Grateful for any assistancel
