If your LMS is reporting the SCORM package is too large, please try one of the following options:

• Request individual SCORM packages, rather than one single SCORM package
• Speak to your LMS administrator to increase the upload limit to at least 500MB.

The media and image assets are compressed within the SCORM package.
