Though images are turned on in this forum, if the link contains a dynamic character, such as a "?" or "&" symbol, the image won't display. This is designed as a security measure.
Great question though ... I had to look it up to see what was going on
To be safe, I think we'll leave the setting as is for the time being, even though this conflicts with images in our own gallery. In your case, you still can link to an image in the FT Gallery, as long as you don't click through to the full image ... not an ideal option, but workable for now at least.
Thanks for pointing this out.
