Hi,

I've found a website that causes mobileOk to crash.

The website is http://www.latavolacalda.co.uk/ (it is the last word in 
web design) and mobileOk throws the exception below.  It could be caused 
by a  transparent GIF image with a wrong format.
Capturing the IndexOutOfBoundsException in the 
HTTPImageResource.checkTransparency method is a solution, despite I 
don't like to catch RuntimeExceptions, so any other idea is welcomed.
