    <p>Your initial function would have run straight into an infinite loop if you didn't have <code>$(this).remove()</code>. Essentially what you were doing was setting the <code>src</code> attribute to <strong>all</strong> <code>img</code> tags, including the preload image itself. (replace <code>$(this).remove()</code> with <code>console.log('loaded')</code> and watch it loop infinitely in Firebug)</p> <p>I would guess that in IE8, once the attribute is set to the preload image as well, it invoked your 'load' event handler first <strong>before</strong> executing the next line which is <code>$(this).remove()</code> (explaining the stack overflow), while other browsers might have first finished executing the entire function first, thus removing the preload image, which prevented the infinite loop. (This is just a guess)</p> <p>A monkey patch to the initial version would be to use <code>.find('img:not(#preload)')</code> instead of just <code>.find('img')</code>.</p> <p>Your patch also prevents the infinite loop because <code>.one()</code> ensures it to only run once.</p> <p>But ultimately I would refactor the function to the following:</p> <pre><code>function switchImage(size, objid, prefix, fullimage){ var $el = $('#' + objid), $image = $el.find('img'), $preload = $('&lt;img&gt;'); if(size !== 'full'){ var image = prefix + size + '/' + size +'_' + fullimage; } else { var image = prefix + size + '/' + fullimage; } $el.data('type', size); $preload .on('load', function () { $image.attr('src', image); }) .attr('src', image); } </code></pre> <p>Also note that the preload image actually does not need to be explicitly appended to the DOM to serve your purpose.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
