Cannot insert images


For some strange reason a ‘file not supported’ error message appears (id. 2500, reason: S3Upload(0)) when i try to insert a PNG file. I believe PNG files are accepted and in fact, this error never showed before. Can anybody help?


@Francesca_DeMatteis please make sure that no firewall or security settings are blocking your editor and the uploading.You can find our recommendations here:

In case it doesn’t help, please share a link to your presentation and send us the image file in question and I’ll be happy to take a look.
