php.net says -
QUOTE
resource imagecreate ( int x_size, int y_size )
imagecreate() returns an image identifier representing a blank image of size
x_size by y_size.
UNQUOTE
So that means (I think!) that he's creating a blank image of a certain size
which he then fills with the contents of a blob from his database.
As this seems to me to be duplication, what advantage (if any) does his that
have over "my" preference, or under what circumstancesd should I choose it?
