It doesn't appear the the H5P plugin is compatible with WP Multisite. I am only able to upload the example modules on the root level of the multisite installation. The plugin shows up on other sites but gives dependency errors when I try uploading the modules.

How can I put some HTML/other rich content into the overlay in a hotspot image, instead of just text?
Thanks for this great project.

We are unable to upload the examples to our WordPress install. When I download the file (zip) and try to upload it I get this message "The file you uploaded is not a valid HTML5 Package (It does not have the .h5p file extension)".

If I change the file extension to .h5p I get this message "The file you uploaded is not a valid HTML5 Package (We are unable to unzip it)".

We are running WordPress 3.9.2 on Windows Server 2008 R2 with PHP 5.4.24
