Maps dissappear from their respective pages

Hey, Im pretty new to roll20 and I wanted to prep a megadungeon campaign. That means lots of maps on pages ready. So I started adding pages with maps on and then started alligning them. Now 2 days later that I started prepping and the first maps I aligned are gone when I open the page. They however still show up on the page tab... Any help? Thanks in advance

Did you delete the graphics from your recent uploads after you placed them on the page?

Yep so you should have them uploaded?

Oh yes. The Recent Uploads in the Art Library is where the file is resident. If you place it on a page, you are placing an instance of the graphic that says "look here for the image". If you delete it from Recent Uploads, there is nothing to refer to. More info: Art Library in general Recent Uploads  read the next section for specific info about deleting images.
