Thanks for reaching out Community regarding uploading a pdf. I apologize for the time you've spent in regard to getting the second page to show as an image.
When you upload a PDF into the Library, a PNG image of only the first page is automatically created.
While we do not currently have a way to create multiple images from a single pdf file, it certainly would be a fantastic feature to have! I can add your idea to our database of customer requests for our developers. We definitely encourage you to click the Feedback button in your account and let our developers know your request directly too! If you have any further questions please feel free to reach out to us here. We are always happy to assist you in any way we can!
I found that I could produce a one-page document by making my page 22 inches long to hold all my content then it would upload a single file
Thanks for sharing this workaround here in the Community! We hope other users find it helpful as well. Please let us know if any questions come up as you continue working in your account.
