Book and book viewer


Hello everybody. I’m building a digital collection of books, composed by many png files (one for each page).
This books should be visualized in the virtual exhibition, but for now It could be enough to put them in the digital library (as you can imagine I’m a beginner).
I’m trying to create this workflow: first, use the Dropbox plugin to upload the files, second: create an item for each book - where I can upload all the page’s file. I can’t add the Universal Viewer plugin in Omeka Classic 2.6.1 and I’m trying without success other plugins (docsviewer, connected carousel and others).
Do you think that the workflow is correct? Have you got any suggestions for the viewer plugin? thank you very much!
