Import files and images on products

I’m in the middle of migrating from VTiger. In VTiger we have a catalog of CD with all there covers as jpg.
Importing the products, stock and prices was succesfull but is there a way I can import all the cover art as well?

Don’t see any import wizard for that. Import it manualy in SQL is not an option because the field label is filled with a random string.

Is there a script for this or an other method for importing files/images.

Did you find a solution to this? I also want to import images via a python script, but did not find a good way to do it.
The string in llx_ecm_files is not random, but probably a hash to avoid handling spaces and weird chars in filenames.
