I had another go with Hugin, the programme that stitches photos together - and despite still not having got around to reading up on how to use it, somehow I pressed things in the right order this time and out came (after my laptop worked itself to exhaustion) an actual proper finished wide format 30MB jpeg image. It would make a forty inch wide print (at 254dpi) - so quite big, and that's without interpolation. How the software managed it with all the junk in these frames, I don't know. I've not looked that closely but I don't think it's messed up on hardly a single thing.
The effect of all that big print readiness is slightly lost when then scrunched to a 800 pixel wide web-friendly version, and it seems to be falling apart in some weird way.
