Not necessarily. There are resources other than Google Images and many users on here contribute content they've shared from other movie image databases but this does mean acquiring images will become quite a bit more difficult especially for more obscure titles.
Yahoo Images however DOES still have the 'view image' button and you can still search for alternate sizes there as well.
But I think it's important to note this recent change as databases like this one will now become even more vital to those of us who use it as a resource.
