Pop-up gallery questions

[ZEBtoonz]

I'm working on a gallery for my new website and I'm trying to get something similar to this website. I'm also following Gary's Workbook 90 at the bottom of the page where you uses pop-up layers for each image. My two questions are the following:

1. When a thumbnail is clicked the popup layer appears but I'd also like for the page to scroll up to the top area where it will appear. I assume I need some kind of a named anchor--could be the word Portfolio?--but I don't know how to achieve this effect. I can only add the link for the popup on the thumbnail. How can I get both?

2. Since each of the popups are on their own layer and only appear when clicking on their thumbnail link, the area at the top of the page below the word Portfolio is blank. How can I put one of the images at the top when the page opens and then have it replaced each time a new thumbnail is clicked?

I won't even ask how I'd achieve having the option of Filters like he has on his page, I think that would be a trip to accomplish--different popups for each category?

Edit: I figured out how to solve #2. I put an image and text on the Mouse-Off layer and then on all the popup layers pasted a rectangle the same color as my page and put it to the back. It may not be the best solution but at least it works.
