Unfortunately I have no experience running Moodle, so I’m not able to help you. Since this thread is not about Moodle I encourage you to create a post about Moodle and OMERO integration.
Alternatively, you can get in touch with the creator of OME Seadragon. He’s quite open to helping others with it.
Dear all, sorry if I was able to get in touch with you only now. I’m Luca Lianas, I work at CRS4 (Center for Advanced Studies, Research and Development in Sardinia) and I’m the developer of the ome_seadragon plugin for OMERO.web.
I’ve been in touch by email with some of the users that are using the software.
Since I’m not an “regular” visitor of this forum, I’d like to suggest to move all the questions related to ome_seadragon to the GitHub repostitory of the project (https://github.com/crs4/ome_seadragon). In there you can compile issues related to software installation or its functioning and I’ll be able to interact with you swiftly, also we’ll be able to create some kind Q&A section.
I also wanted you to know that at the following link https://github.com/lucalianas/ome_seadragon_compose you can find the docker-compose file with the full stack needed by ome_seadragon to work. You can use this as base to install the software by using Docker or to know how it can be configured.
I hope this message was usefull. See you on GitHub!
