Total pain then Boo 
Frankly if they have the scanning and indexing done then the tricky work is all done. Loading them up is just a trivial process (they already have all the infrastructure in place for other images so no need to create anything new) and we are only talking about a few GB's of storage. Sounds like a lack of impetus from one side or the other 
Whilst I understand your frustration and would also love to have free, online access to the images, I think you are being slightly unfair to the LDS (the Durham side have finished their side of it and, as far as I am aware do not 'have' digital copies as the LDS have not yet finished doing whatever techy stuff they need to do to the images they scanned).
Bear in mind that without the LDS's many years of work, at what must have been enormous cost both time wise and financially, most of us would be dead in the water as far as research goes. They travelled the world scanning records, for their own, religion based, purposes. This helped to preserve the records for future generations. Then they indexed them to make it easy to find who you were looking for.
Having done that, they did, and still do, share the information freely with non church members, such as myself.
Though the Durham wills are high on our list of priorities, we just have to accept that its a drop in the ocean compared to the records of the entire world. I don't contribute financially to the work (though I have done some transcribing for their projects as a little 'payback' for their generosity)
I'll accept that the LDS will put these online as and when their resources permit, in the meantime, as I did last week, I'll print out the form and send it off and wait 4 weeks to see if they can be copied and then I'll pay the £6 each and wait for the copies to arrive :-)
I'll get what I want :-)
Boo
