@d-healey Thankyou, as usual your help was invaluable.
Ironically I have been using autocomplete quite a bit recently but it didn't even occur to me in this case.
Thanks again, it is doing what I want it to do now
Turning off custom graphics (unintuitively) fixed my main issue.
Now your mentioned problem comes into play not getting my image names correctly, but I should be able to fix that.
