I'm working on a simple HTML web gallery plugin. I would like to include an optional introductory page with a single image from the gallery, chosen by the user, at an extra large size, with some introductory text about the images in the gallery.
I can create the single page with AddPage in manifest.lrweb. I can export ALL the images at the extra large size by adding to the model in galleryInfo.lrweb.
But what I really want is to have the plugin export just the single image that the user has chosen for the introductory page at the extra large size, or even export no extra large images if the user has chosen not to include an introductory page at all.
I can't immediately see how this might be done. Any pointers as to how I might achieve this would be much appreciated.
