Image Hotspots via H5P.org

Hello!

I would like to use the Image Hotspot feature from H5P.org, and then self-host the content on our own website via with WordPress plug-in. Is this possible to do only with H5P.org? Or do I need to sign-up for an H5P.com account as well? My institution cannot budget for the yearly subscription service cost on H5P.com, and we will not be emedding it into Brightspace, for example. We only want to use the Image Hotspot on our website.

Thanks for your help!
