New Installation of Omeka-S and IIIF Server

Hello everyone,

Our institution is looking at installing an instance of Omeka-S for our university wide collections and exhibitions. What i am trying to understand is the relation to the IIIF server. Would it be good practice to install our own IIIF server to host the images, and have Omeka-S items point to them?

Or is that the job of the Omeka-S IIIF Server plug-in?

I would be curious then, if they are separate, in terms of installation if it matters which is installed first.

Would appreciate your advice,

Sanjin
