With the exception of ‘below’ none of the others produced any title at all below the thumbnail.
That’s correct – the other options are not supposed to produce the titles below the thumbnails. The “tooltip” option displays a tooltip upon hovering, the default HTML title displays a standard yellowish title when you hover, and the other options show a small overlay above the thumbnails at the bottom.
The titles are right justified and correctly below each thumbnail until you get to the first thumbnail which is portrait and not landscape.
Actually, that is not what’s happening. What is happening is what I had outlined previously – each title is being displayed at a 500px width for landscapes and 333px for portraits. For your landscape photos it appears to be right-justified, but it isn’t. If you observe carefully, the title spills over the photo edge. I can see that the code is being called correctly, but for some reason the title widths are not getting refreshed until you load more photos.
Since I have never encountered this issue previously, I suggested adopting a different title display style.
I see that you have been using Photonic for about 4 years now. So, was this working previously and did it suddenly stop working? If so, what changed recently? Photonic has not been updated for over 7 months now, so I doubt this was caused by any update to Photonic.
