Adding image alt tag to twig template

Archive

Can’t find a way to add an alt"" tag based on the imagename to every image. In my template i’m adding the images like this:

{% for image in page.media.images %}



  • {{ image.lightbox(1024,768).cropResize(215,215).html }}


    • {% endfor %}

    The .html action accepts an alt tag: see docs
