Selecting Images & Placement on the Page

Hi,

I am creating a website with several different portfolios or galleries using the Highend theme. I have uploaded a bunch of photos and want to create separate portfolios on separate pages. I am having trouble doing this using tags and then excluding certain images from certain portfolios as there’s cross-over between the pictures on the different pages. For example, if one page has pictures A and B and a different page has pictures B and C, how do I get picture B to appear on both pages? Is there an easy way to create different portfolios in the current theme or can you recommend a good plugin?

Also, is it possible to use a portfolio page template and add content beneath the portfolio? Using the Highend Theme, the portfolio automatically goes to the bottom of the page.

Thank you SO much for your assistance! It’s much appreciated
