Could those of us who are not builders, but who like photography, help too? We'd need a steer as to the sort of thing you'd want and the format you'd need it in.

It would be great if non builders would support this!
What is a good texture ? I will give my opinion and hope others will add to this.
A good texture differs a lot from a good photo for sure, because the composition is not important its the material and detail.
I hope i can explain it with my bad english.
First of all the best textures are very often made during cloudy days.
The picture must have an equal lightning on each point.
No shadows., no glowing.
the only shadows allowed are from the heights difference in the texture itself.
(the shadow must made be inside the modelling program depending on the object)
deeper inside is most of the time a bit darker.
the photo is from an absolute frontview.
It must be sharp. and lightning is in the middle of the spectrum.
(we change that inside Blender or 3dMax by adding or subtracting greyvalues)
As less distortion as possible!
A horizontal line will a get a curve from the lens. that curve must as straight as possible.
the photo has to be the material itself in most cases and often is a closeup that can be made seamless.
a picture of a flower or a leaf is best when it can be separated easily from its background.
Patterns!
patterns from ornaments for instance , but dont forget also to deliver a pic the material of the ornament, so give a set of pictures belonging together.
Photo's of cracks in walls.etc
This is it in a first glance, but i will come back later wit some examples of good and wrong.
