Could it be failing on your query?
jQuery(' > img', this).attr(alt);
I beleive that there has to be something before the >. The way it's set,
you're saying all img tags that are the child of nothing.
jQuery('body > img', this).attr(alt);
might be better, but I don't know what you're looking for precisely.

Subject: [jQuery] Re: jQuery to create dynamic HTML-Content in a table
If i use
uid = jQuery(' > img', this).attr(alt);
no more code after this line is being executed :(
E.g.:
[code]
$('table tr:eq(0) td:gt(0)').each(function(i) {
// If it's a col that contains an <img> (than the <td> has
the class
'imgg')
if($(this).is('.imgg'))
{
alert(i);
$(this).append('#1');
// Read out img's alt-attribute and save to array
uid = jQuery('> img', this).attr(alt);
uids[ i ] = uid;
// Testoutput to the matched header-column
$(this).append('#2');
}
});
[/code]
#1 is prepended, but #2 not :( And #1 only for the first <td> even though
there are more matched td's ...
