utterly bizzare but it is true. When the page gets to the second div full of ol elements styled to show articles it has a chunk of html

<img id="hpali_103416" alt="Raspberry Pi: 27 Jahre alter Mac Plus surft im Netz" src="/1312/103416-70137-i_rc.jpg" class="golem-data-afterload" data-src-high="/1312/103416-hires140.jpg" data-src="/1312/103416-70137-i_rc.jpg">

and NetSurf never even tries to fetch the source image (not in the log)

for comparison the ol five lines higher in the source has

<img id="hpali_103441" alt="Samsung: Android 4.3 für das Galaxy Note 2 ist da" src="/1312/103441-42263-i_rc.jpg" class="golem-data-afterload" data-src-high="/1312/103441-hires140.jpg" data-src="/1312/103441-42263-i_rc.jpg">

and the image is fetched and displayed just fine

The ones we don't fetch have an empty src attribute, and JavaScript to copy the data-src attribute value into the src attribute when you scroll down the page. They do it to avoid fetching images that you won't see if you don't scroll down, and they do it to speed up page load and/or reduce their own bandwidth.

Not really a bug. It won't work without JS and we're nowhere near implementing enough JS for this.
