nit: please use a switch/case above so that if the enum gets a new value,
the compiler will complain about an unimplemented case in the switch
statement.
why the static cast in the BMP case? That shouldn't be necessary given
that BMPImageDecoder inherits from ImageDecoder.

WebSize has a constructor that takes an IntSize, so you should be able to
just write:
return m_private->size();

nit: no need to assign numbers to the enum values. just let
the default 0 and 1 be used.

normally, WebData is passed using a "const WebData&". why make it a
pointer instead?

maybe this method should be called getFrameAtIndex for consistency with
the frameCount and isFrameCompleteAtIndex methods.
