I bought Gridly recently and installed it here:
It works fine, but there are irritating limitations.
1/ Could it please be set so one of the fields (alt text or title - or a new custom field?) shows up as hover text (ideally on thumbs in the grid as well as enlargements)?
2/ could it please be set so one of the fields (alt text or title - or a new custom field?) appears on enlargements? At present, i can only get labels to appear on the grid images, not the enlargements. This is especially annoying because when viewed on a mobile device even the grid labels don't show up properly - so mobile phone users never get to see accompanying text in full.
These changes would make this a very useful and attractive section. Without them, I think it's rather limited as a way of presenting information.
