Nicely done. I have a kit and was thinking of finishing it in this scheme.
As to being able to view the images, I cannot see the images when I use Google Chrome but I do see them when I use Microsoft Edge or Firefox.
I notice that the images are hosted on a web site / page that shows as being not secure ( i.e. HTTP vs HTTPS ).
I seem to recall that Google Chrome had some changes with respect to non secure sites. Perhaps it is the combination of cross linking from a secure site i.e.
https://forum.ww1aircraftmodel (... etc ) to a non secure site i.e.
http://www.primrose- ( ... etc ) which is causing the issue with Google Chrome ?
I tried just viewing the individual images with Chrome by copying an image's url while viewing in Microsoft Edge and the image views normally in Chrome which makes me wonder if the problem lies with cross posting comment I described just above.
I have tried changing some of the privacy and security settings in Chrome to no avail, perhaps I just haven't found that magic combination yet.
It is indeed frustrating, particularly when when you just can't put your finger on the problem so that it can be fixed.
cheers, Graham
