the doc says that the function 'exif_thumbnail' is enable in php4.3 (my
version) but I've the message 'undefined function' when I use it. Why ? Any
I've the gd lib even it's not necessary.
it seems, that youre PHP is compiled without exif or exif is disabled.
Yust load the extension using dl(php_exif.so) or dl(php_exif.dll) on
Windows OS. Exif reqires on Windows also the mbstring extension.
