Isn't it significant
that they were still holding hands an hour later?

if the image quality is poor but there is still something that you think is important you can always type that info into one of the images which is saved.

There's more to it
I intended these photos as a series whose subject is
courtship and
mating. That's why I included shooting times. Lynette removed not just this photo but also the first one, in which the spiders begin to approach each other. Photo quality in that earliest photo is even worse--I saw something happening, which I thought was the beginning of a fight, and hurried to capture the moment--but it's the only one I have that shows the early phase.
Photo quality in this picture is as it is because the spiders were below two layers of web. I don't believe that a statement that they were still holding hands, etc., would adequately replace the photo. First off, "holding hands" was a quick, anthropomorphic way of describing their postures, and it isn't accurate. Better to show how they were actually aligned, having withdrawn from each other but not very far, and still touching. Then there's the pool of seminal fluid on the upper web. The side views of the actual copulatory act, or a near approach to it, don't make this clear.
The guidelines somewhere say you can dispute a frassing. Well, I want to dispute this one. From many photos taken at the scene, I chose a few to document a behavioral routine. The point isn't what the animal looks like, as in so many that simply present a specimen for ID; it's what the animal does. The behavior around mating in this group of spiders (all sheet webs? not sure) counters the popular stereotype that mating females treat males viciously, the classic model being black widows. What I observed was leisurely--that's why the shooting times are important--and gentle. There was no violent aftermath, quite the opposite. This pair appeared to remain friends, if that concept applies. They separated slowly after copulation, and the male lived in the female's web for days afterward.
I hope I've made a good enough case for keeping this series intact.

I don't think it's a good idea
to keep poor images to tell a story. Like John mentions the story can be told in words on the good images. However, if you are attached to these particular images then feel free to link them back to the others and move them back into the guide.

Let's split the difference
I
am
attached to keeping them together. In this case, the photo shows the behavior and the environment better than words would. Its quality isn't bad, considering the webs between spiders and lens. I've put this one back into the series. I left the first image, the pair approaching each other at a short distance, in Frass and edited my comment on the (new) first image (old second image) to describe the deleted photo and start the timeline. That photo was of worse quality and didn't show anything too hard to describe.
