Unbelievable! My quilling on a book cover... without my permission

Sometimes I stumble upon my texts and images, stolen by other websites. Sometimes I see copies of my designs, published on the Web without mentioning me. Sometimes I even blog about plagiarism. But what I've seen 10 minutes ago was just "above and beyond"! My photograph of my quilled butterfly had been used for a Russian book cover! They are going to publish the book by March 8. I'm not sure if my text, designs or images had been used inside the book, but the cover is more than enough.

If you don't recognize the picture on the screenshot, look at my Quilled butterfly in a fishbowl.

UPD: Thanks for your support!

I want to say a big "Thank you!" to everybody who supported me in this unpleasant situation. I received a letter from the publisher, and they assured me that the cover will be changed and the content will be completely original, written by their author. They blame the designer, who made the cover and let down both the author and the publisher.
