a title for each image ...

Hi,

1. Each image has a title which is displayed by default below the image. Of course, this can be changed with a layout override and some CSS to make it display on hover.
2. Check the "Wall" layout at the demo page which is almost the same as Masonry but more lightweight. Showtime includes the "Justified" layout which is also a good alternative. If those layouts do not fit your needs we can help you build a layout override for Showtime Image Gallery and integrate the original Masonry script.
3. No, there is no integration between Econa and Showtime. They are two different custom fields.

Please let me know if you have more questions.

Regards
