Global labelling of images in galleries

OK, I am able to get the images in a gallery to use the image name by using the label and smart field options. However that still means adding a label to each image individually, on large galleries that’s still very time consuming. What I would like is to be able to insert label on first image, adjust box to a size that will accommodate all the text and then have that insert in all the images in the gallery?
Is that possible and/or am I missing something that’s already there?

I have had problems even getting the labelling to work , raised this with Duncan and he is looking into it !

I have now got it working! I was missing how to apply to all images and have now found how to!


please enlighten me as to how you solved the problem , still having diffs here with putting on the label
