Thanks for the reply.  I was away from my Mac for about an hour, went to my website, did a refresh and everything now appear as it should.  I find this very weird.  I didn't change or upload anything.  Any ideas why this happened in the first place?

I just upgraded to the Pro version and am having an issue with the web gallery that's being created.  The gallery I just created contains 64 photos.  Everything works perfectly for the first 50, however, the thumbnail images from 51-64 are blank.  If clicked on the full-size image appears properly.

I've deleted and recreated the gallery several times.  I've shut-down and restarted Lightroom, but have had zero success.

Can anyone help?  The gallery is for an event I shot and 50 people are currently waiting to see photos.  Help!!
