With the help of community member OneSidedDie, I’ve now updated the High Quality Image pack with ~200 new images. You’ll have to redownload the whole image pack again to get those I needed to update the existing package (rather than uploading a new file) because I’ve fixed the card Martyr’s Mirror which had the “Martyr’s Cross” image wrongly. So I decided to repackage.
It’s a big download (~170 Mb) but worth it.
I’ve also updated the low quality pack and removed the cards I’ve just put in the high quality pack. You should redownload that if you’re going to use it, or you can just make sure you install it first, so that the low quality images are overwritten afterwards.
