Hi Martin,
Sintax is: $('selector', [context])
When you set the optional parameter context for a jQuery selector
you are saying: "Match all 'selector' against the contents of context".
The default context is HTML element.
Please go to and open the tab "Examples":
http://docs.jquery.com/Core/jQuery#expressioncontext
Hi Mauricio,
...
One question: I don't quiteunderstand the bit where it says "$('img:eq(0)', this)". Best regards,Martin
