I am not sure. I think you should be able to edit the imageData.xml file after you have made the gallery in JAlbum. Use WordPad or NotePad or similar text editor to edit the xml file.
I prepare all the images and thumbnails in Photoshop. Then I manually edit the gallery.xml(imageData.xml) to add the file names and captions. I haven't graduated to using a script. I copy the images to the images and thumbnails folders then I copy all the files and folders to a new folder on my web server via ftp.

My SimpleViewer Gallery:
I think right click will only work on the main image, not the thumbnails.
PS There might be someone else who can help better. If you post your question again I will stay out.
