Hi JanMIkal! If you go to "My Marketplace Items" under your account name, you will find links to all of your purchases. If you click on them to visit the marketplace entry for each item, there will be a download link, if the creator has opted to provide one. Most do, in my experience. For items not easily downloadable, you can download any image on a one by one basis by selecting it in the VTT, pressing "Z" fpr the preview, and right-clicking and saving to disk. Compendium content, and adventure text is very difficult to download in anything but a copy/paste operation. Since it has been optimized for VTT use, it is of limited value in its existing form outside of Roll20 anyway.
