You can upload a thumbnail per page to show the page in a more visual manner. We accept JPG, GIF, PNG files, and PDF files. If you upload a PDF we will transform it to something like a JPG.
There are two ways to upload a thumbnail. The first is on the Edit Page, you can upload an individual thumbnail.
The second way, is to bulk-upload thumbnails for multiple pages at once. The way this is done, is to a) select multiple pages by clicking on the drag handle of each page, or click on the first drag handle, and use SHIFT-click on the next drag handle to select many consecutive pages at once.
Then, you will need to upload a PDF that contains one thumbnail per page. Each selected page, will be assigned a page within the PDF starting with the first PDF page. Only put as many thumbnails as you want to upload into the PDF, based on the order of the selected pages.
You an choose to show or hide your thumbnails using the View Options menu.
If you want to look at a bigger version of the thumbnail you uploaded - you can click the "quick look" in the bottom right corner of each page.
