I did manage to get this working on my first attempt and I can now see some images in the blogs I've had pocket grab for me.
However it's definitely still missing some images and I'm wondering that since the first post hasn't been updated for a couple of years if I'm using out of date files.
Looking at it a bit more it seems to be gif that aren't being sorted

Here's a blog that it doesn't work correctly on. I get none of the screenshots but I do get the picture of the manual page and the final picture of a map. They all seem to be gifs though. I have verified that they're proper compliant gifs.
My guess now is Magick isn't able to convert some of them and I can't work out why.
EDIT :
It's pocket to blame here. It is not grabbing all the images, nothing to do with the Kobo
