Well, this depends on your definition of "best."  The procedure you 
describe is almost certainly best in terms of ease and reliability, 
since it will work for any image format your OS knows how to interpret. 
 It's probably not best in terms of efficiency, though.  If you know 
your images will be large and of a specific format, then you might want 
to download just the first so-many bytes and parse the image header to 
get the size.
Best,
