Known issues with HTTPS?

Are you aware of issues with images not uploading under HTTPS?

There have been several other host issues unrelated to the plugin so the images may not be uploading because of those. Just wanted to rule out the security aspect. I could have sworn it was working after we installed the security certificate but I could have been loading the unsecure URL.
