I downloaded a Lightroom print template from http://www.jilllevenhagenphotography.com and then did a print to file as jpg export for this FB Timeline. The only thing I could not work out was how to run the text to two lines (did it in PSP in the end), and I would have prefered to fade the opacity of the background a little, but at least it was not complicated & working directly from LR will save time.
Thanks go to my daughter who patiently sat while I worked out how to use my new 5-in-one reflector!
