Hi Keith,
Well done on the shots - they look great!
A small comment (not even a tip - it may be different with you) is that 4*6, 7*5 and 10*8 are not a large enough range. We dropped 7*5 completely. We could have been wrong, but....
Also, we offer an electronic version, many of these folks breed their dogs, and need good images for web sites.
As to you question: Do you happen to know if two different sets of Special Instructions in PM would result in the same image showing up in two different locations on an EOS template?
well, any specific image can only have 1 specific special instruction, so it will only show up in 1 place in the gallery. If you want to put an image into another gallery, you either need to have another copy of that file in the directory your going to turn into a PM gallery, or use some kind of fancy filtering on one large directory (sounds tricky). Anyway, if you have 2 copies of the file, each copy can have a different special instructions. If you've only 1 copy, it can only have 1 special instructions.
Perhaps I'm not understanding what your thinking of doing?
