Thanks Nigel. I had never read that FAQ – and it holds the answer. The media items which had caused me to question the validity of the Slide Show code actually had NO type defined, so album placed them in ‘Other’ and media edit showed it’s default of ‘photo’ because there was no type and this was only added when I hit save. Following the guidance in the FAQ, I have listed all the media items with no ‘type’ – there are quite a lot of them – all created a long time ago – probably at the time I first transferred my data to PGV. I shall work my way slowly through them to enter the correct type, and will also correct the few items with erroneous type. So it’s been a useful exercise in cleaning up my data! Thanks for helping me get there!
