First of all, these aren't copyrighted images. I don't care who takes them. Just don't use them for nefarious purposes.
But if you actually want to have a print-quality image, you need to contact me and get it directly. The images you download suck. That's just the way Blogger does it. If I could do it any other way, I would.
Anyway, I'm happy to pass anything along. Email, text, tweet. Whatever. Just let me know.
