$im_types = @ImageTypes();
  echo "Error";
  if($im_types & IMG_JPG)

-> Error is echoed.

php_info() says:

GD support enabled
GD version between 1.3 and 1.6.1
GIF Read Support enabled
GIF Create Support enabled

The same script with PHP4.0.3pl1 and PHP4.0.6 acts as expected.

Remove the @ before ImageTypes. Does it print a error now?
 [2002-01-09 02:10 UTC]
No feedback. Closing.

Sorry for the late feedback. No Error after removing the @. Reopened.

I have tested this on several different versions of PHP and GDLib and it doesn't work if the configure doesn't find your libpng and libjpeg.

If you carefully read the output of the configure
script you realize that maybe libpng and libjpeg
isn't found even if you have them installed in default
locations. I have tested this both on RedHat7.1 and SuSE7.3
and I had to specify the paths myself to make it work.

'./configure' '--with-apache=../apache_1.3.23' '--with-zlib-dir=/usr/lib' '--with-ftp' '--with-png-dir=/usr/lib' '--with-jpeg-dir=/usr/lib' '--with-gd=../gd-1.8.4' '--disable-debug' '--with-sybase-ct=/opt/sybase-11.9.2' 

If I leave out --with-png-dir and --with-jpeg-dir imagetypes() returns nothing. You can also check the output
of phpinfo() and you will see that the GD Support is enabled but it doesn't say anything about PNG and JPEG support being enabled.

So don't forget to specify your libpng and libjpeg dirs...

In this case, the problem is gif support related. As I wrote php_info() returns that gif support is enabled, but ImageTypes() does not. This absolutely makes no sense to me.

We have the same issue on both Red Hat 7.2 and FreeBSD; there has been some discussion on the Typo3 mailing list ( as well -- apparently there are others who have experienced this. It appears to occur at a minimum in 4.1.0 and 4.1.2, but not <=4.0.6
