Can warning be displayed before category is viewed?

[elink]

Firstly congratulations on the excellent products, Phoca is just great.

I have medical graphic photos of workplace accidents and injuries listed in a single category. Does anyone know of a way I could place a "warning page notice" prior to a user viewing this particular content category? or any suggestions of a work around?
Thanks I appreciate any help. the url is http://www.MiningWA.com.au

Hi, maybe you can write it into the category description, or you can do some javascript popup alert on your site, so before user will visit the site, the javascript alert window will be displayed where user should confirm it.

Thanks so much for your suggestions, I appreciate your input. I had another suggestion as a temporary fix and that was to embed into an article with a warning notice at the top then a page break so the user had to click next to see the rest of the article which had the images.
Anyway thanks again
