Thanks everyone for your replies, especially Forseti and Harry for your useful info. - I appreciate it, thanks.
The reason i asked the question was that in my own gallery i have 1 photo which when clicked on gives the exif data, the other 2 (although i put them in in exactly the same way) don't seem to show any info.
I wondered if it was something i was doing, but i guess it's just the foibles of this site at the moment. Until it's completely sorted and proven then i will remain reluctant to post many images on here.
To answer Gil - for me, as a beginner to this hobby, it is quite useful to see how more experienced photographers have gone about their art. It is quite difficult at times to get feedback (although i have to say that i did get some good advice on the old DCM site) and this just helps to fit another litlle piece of the jigsaw. I do think you're very brave, though Gil, admitting to the fact that your underwear is "EXTENSIVE", "informative" but "exceptionally BORING" !
Cheers, Sie
