FWIW what Flickr are doing _today_ when they don't have text appears
to be just setting alt="photo".

Photo page of latest upload on Flickr at time of writing has

   <img id="liquid-photo" alt="photo" aria-describedby="title_div"
width="640" height="427"
style="visibility: visible; ">

    <h1 id="title_div" property="dc:title" class="photo-title">IMG_7354.jpg</h1>


They link to that page with:

    <img src="https://farm9.staticflickr.com/8005/7688297284_4a72f82f25_t.jpg"
width="100" height="67" alt="IMG_7354.jpg by sarahannward"
class="pc_img" border="0">
