[Javascript] An image loader working in FF but not in Opera, Safari...

[Troy III Ajnej]

I have to agree with Hakan,
the 'get elements by tag name' will return a collection of the specified tag 
that doesn't have any directly connected properties with that tag type.
The only chance that this script will work is, only if you have just one IMG 
in the coll, so the script returns entity not the collection and you will be 
able to get the 'complete' property of it.
otherwise, this script is broken, nonworking for all other cases where 
you've inserted more than one image inside the 'content' container.
If this is the case, non of the browsers will do the magic. You will get 
error containing somethin like can't get complete property from the 
collection

regards
