Unable to read imported images

I’m trying to import an image to use as the background for my animation. However, when I’m in the import window and I select the image I want, it says “Unable to read” (followed by the file path to the image) This only happens with a specific set of images that I want to import. They are all very large JPG images (30-50MB each) so my guess is that there might be a max file size that can be imported in Harmony? The reason they’re so big is because they are very long in length because I want them to slowly pan across the frame in the background, with my animation in the foreground. What are the limits for image file sizes? I might be able to manage to cut them by about half but that’s about it, as they still need to be high quality.

I’m having the same problem. Have you found the solution for this?
