[Koha] How to host eBooks, Images for Readers

Hello Everyone, I have setup the library for the books and now I have few eBooks, scanned images of rare books. I would like to integrate those too in Koha, which will be accessible to the readers. Please let me know any guide available for the same? -- Thanks, Laxmilal Menaria | +91 982 955 3793 | http://laxmilalmenaria.com/
