Hi,
1). kindly find attached the photos.
2). kinldy find the attached photos.
I'm inclined to choose A. I never write it myself, but I've seen this expression so often that it seems OK to me, although perhaps I've allowed myself to be corrupted by business jargon. I see attached as more adverbial, relating to find, than adjectival relating to photos.
It's an odd expression, really. When you think about it, it should usually be 'included' rather than 'attached', shouldn't it? If something is 'attached', it seems almost insulting to imply that I may overlook it.
Best wishes, Clive
