F.R.G. Does not recognise .jpeg map files from National Library of Scotland

[bwmoths]

Adding a map generated by the National Library of Scotland (N.L.S.) website - https://maps.nls.uk - which are labelled as .jpeg - these files are apparently not recognised by the "Add Raster" function. Maps from N.L.S. labelled as .png are recognised and I believe maps from other sources labelled as ,jpg are recognised.
