How can I add a 'Back to Gallery' button to my PostcardViewer. I successfully added one to my SimpleViewer, but no luck here.

PROBLEM RESOLVED! Works perfect.
I changed the screen resolution from 1024x768 to 1280x1024 and all went well. Thank you Felix, for the simple solution for the SimpleViewer.

I downloaded Simpleviewer (several tries) and when I try to build my web gallery in Photoshop CS3, the actual Simpleviewer drop-down window is cut off just below Gallery Title (input). The 'Cancel' and 'Build Web Gallery' buttons are not there. Help.
