Not yet. But if you know how to find the corresponding picture file for a music file, then it can be done quite easily. You can extend the FtpUpload add-in of Raduga 3.8, which uploads an HTML file to a web server. If you have a corresponding image file, then you could upload it as well.
I work with the demo 3.5 and i will look if i can do something. It must be possible this will be a nice mission after my holiday. You hear from me again.
