Hi Tim,
Can you tell us where the pictures that you want to upload are saved?
Are they on your harddrive, or on Google Drive or something similar? Or do you use a hosting service like Imgur, Flickr or PostImage.
If we have some more information, we may be able to help you.
Meanwhile, I am glad to see a fellow Handley Page enthusiast here. This is a very nice alternative colour scheme. I guess this is the 1459 from 1917?
I think you have done a well executed conversion of the Airfix kit,
Hats off!
Willem
