When I said above that 'the gallery itself scales OK', I also added that 'the thumbnails do not increase in size'.
In other words, thumbnails never change in size in a SimpleViewer gallery embedded in an HTML page (whether the gallery dynamically resizes when the user resizes the browser window or when the user changes the page's zoom value). This behavior is consistent with a SimpleViewer gallery embedded in a PDF file when the user changes the file's zoom value. The thumbnails always remain at the size determined by the thumbWidth and thumbHeight configuration options. This cannot be changed.
I am setting the thumbnail size in the Images tab. The rest of the slideshow scales while the thumbs remain static at 50 pixels.
This happens by design. The main image dynamically resizes but the thumbnails remain at the thumbWidth and thumbHeight dimensions.
Is there another way to reduce the size of the thumbnails in the Customize tab instead of the Images tab so these thumbs scale with the rest of the slideshow when embedded in my pdf?
No. When you set the thumbnail dimensions on the 'Images' tab, svBuilder-Pro creates thumbnails at the specified size and sets the thumbWidth and thumbHeight configuration options accordingly. There is no other way to set the thumbnail dimensions or to have them scale dynamically when the size of the gallery is changed (by a change of browser window size or by zooming).
