He could upload his images into the forum gallery, This would also give him a url for the images.

I don't visit many forums these days, other than ubb forums, so don't know if in line uploads are out there in the big world.
The new upload manager is a huge step forward.
We now have a solid modern base forum, the new features are not that far away, I dont know what they are but we are coming out of the darkness.
