Forward & Back triggers for a popup

[rafsgrafx]

Greetings all.

I'm creating a project which I'd like to employ some 'back/ forward' trigger buttons allowing an image scroll (6 to 7 images). Once the user stops at an image of interest, clicking it will launch a larger image popup window. See attached jpg.

At this initial brainstorming & design stage, I'm not sure if Xara would be the best vehicle for this endeaver. Hopefully it is. Any and all suggestions along with alternate solutions are welcomed.

Thnx.
