it was brought to my attention that file uploads larger than 100 MB were failing with a connection error. AstroBin has one of its strength with the offering of unlimited storage space to its premium members, and not applying any compression to your high quality images, so I have raised the limit to 200 MB. It's a practical limit of course, not an artificial one. But I believe that should be enough even for very large mosaics!

Hope you find this useful!
