DW7 I just checked, and in that course, the images are linked to https://static.memrise.com/uploads/mems/<filename>.jpg
. That is, the course's pictures were mems :/ I'm not sure how this happened, but it looks like these pictures were probably lost when mems were removed.
There are several courses like this. I suppose I should add some code so that these courses can be uploaded without their images, and then you can re-add the images (if you wish), once we're able to upload images via the website.
