It would be great to be able to add alt text to the img tag for the slide image using Galleria's extend option. I can easily alter the markup in imageTarget each time the image loads, however imageTarget is not available on the first slide.

To duplicate the issue, make a view using Views Slideshow: Galleria then put the following code in the view settings under Format: Slideshow Settings > Galleria Options > Advanced Settings > extend field:

function() { this.bind(Galleria.IMAGE, function(e) { Galleria.log(e.imageTarget) }); }

In the console, you'll see "null" on the first image.

(I don't experience this issue using the standard Galleria format without Views Slideshow.)
