While adding books to my collection, it would be nice to be able to search and download bookcovers from within Tellico. Now I have to seperately use my browser to search for an image, download it and add it to Tellico. That's a bit of a tedious proces.
There are a large number of source for downloading book covers from within Tellico already. Is there one in particular that you are missing? Right-click on a book, and select "Update Entry".
You can also drag and drop images from your browser or file explorer into Tellico's Entry Edit Dialog, which should make it easier - instead of having to download the image and add it separately.
