I'm very sorry for this inconvenience.
I have had some discussions with a friend recently involving European copyright, art and similar topics, and it came to my attention that technically, by using the pictures of an artist without their permission, regardless of whether I was crediting them, I did a potentially punishable offense.
Because of this, because I work in an environment where I want to be on good terms with the artist community, and because I want artists to get their fair share, I decided that I couldn't just keep on using their art like that. Whoever has followed me on BGG might know that I did some other custom stuff there, too. Over there, I have been starting to co-op with artists to get my foreign art replaced with original art.
For Dominion, this entire process seems unfeasible. There are just so many cards, and I honestly am not as interested in the game anymore. Yesterday I played the first game in years. Approaching tens, perhaps over 100 artists about each work I currently use, picking replacements etc just seemed too much regarding it's not something I love anymore. So I decided to delete my imgur images without replacement, trusting that my cards were documented well enough by other users of the community to retrieve them, if there should be interest.
I still have all most of the files as they were posted here and am quite willing to send anybody interested a link where they can be downloaded for personal use. Also, If anybody likes to, feel free to do new art for them.
I hope this answers some questions I may have caused. Also, I hope you all had an excellent transition into the new year.
