I am using the free version.
The normal size flip book works perfectly and I want to share news of the plugin with my friends on Facebook / Instagram but...
when I load the PDF in 3D flipbook > add new, the icon which should show the front page of the flip book, just shows a small broken Icon.
However the flip book then loads fine ...but full size on to the page, I would like to to load a thumbnail version (then use lightbox option to increase the size of the pages when you click on them).
Is the problem the size of my PDF, I have changed it from A4 layout to A5 but I have had to save it as 'Print' quality, to get a good resolution?
