Well, I’m not sure what happened between when I looked earlier and just now, but the two URLs now definitely map to the same image (they’re bitwise identical files). The original (pre-Fark-caching) URLs are:
Reflections 4: http://www.andyshirleyphotography.com/Prints/Flowers/i-LBM7m2W/1/XL/Ommegang-Tour-and-Tasting-9-XL.jpg
Booze 2: http://www.andyshirleyphotography.com/Prints/Flowers/i-LBM7m2W/1/XL/Ommegang%20Tour%20and%20Tasting-9-XL.jpg
Note that they’re unique files with the difference in file names being spaces in the Booze URL versus dashes in the Reflections URL, but if you download both image files separately and compare them, they’re identical. Even the Fark cached versions from the contest pages are identical.
When I looked before, I swear the Reflections image was a less-saturated version of the Booze image, but I can’t explain the discrepancy, unless… Can you get sloshed from looking at pictures of booze? 🙂
