Error inserting images in Course Presentation

Every time I try to insert an image on a slide in a Course Presentation in WordPress, I get an error message.  I've tried jpg, png and gif formats.  Every time I try, it starts to upload, gets to about 10%, and then shows the message, "File type isn't allowed."  The images are PowerPoint slides that were converted into individual images so I can preserve the layout. Any ideas why I can't insert an image?

Thank you,

Hi Nancy,

Please change the file extension from .JPG to .jpg (lower case). There is a bug in WP H5P plugin that you cannot upload anything that has a file extension in upper case.


Will do--thank you so much!
