So, every image that is on my normal BYC page is accurate, and you can use it. Several additional images that I have found are here. I have forgotten/lost what dimensions you said would be appropriate--as a test picture, tell me if these dimesions are big enough.
I will try to take some pictures of modifications that we have made, but it is both getting dark and raining here, so I will try to get those soon. I was also thinking it might be useful to upload a nicer picture of the original, handrawn plans.
I will try to get this more complete in the next few days, but tell me if you think this is an okay medium to work in (via the BYC page) if not, I can try out your FTP thing.
