Rich, thanks for taking the time to respond, especially with that video (now saved).
This not only gave direction but highlighted two areas which may have tripped me up, the 'select all' option but needs to be activated by clicking on layer, also the 'click in the middle' reference (1.38) also applies to other similar tutorials, Lastly the rounded rectangle option, nothing shows immediately which probably led to me trying something else clicking merrily away.
On another note I came across this tutorial (before reading your reply) which worked first time, exported as JPEG and uploaded without issue.
GIMP 12.7 Round corners
In future will look further back in Google search results, or better still query this database direct.
Much appreciated.
