# Cannot create thumbnails

 * I am not able to create thumbnails when uploading images to WP. Here is my configuration:
 * Fedora Core 4
    Apache 2.0.54 (rpm) PHP 5.0.4 (rpm) with php-devel, php-gd, php-
   mysql, php-pear, php-ldap, and php-mbstring GD 2.0.33 (rpm) with gd-devel
 * When I first installed WP, I would get the error “Filetype not supported. Thumbnail
   not created.” whenever I tried to create a thumbnail. After reading the message
   boards, I realized I needed gd support for php. I then installed the php-gd rpm.
   I checked my phpinfo and now I have gd support enabled.
 * Now when I try to create a thumbnail, instead of getting the “Filetype not supported”
   error, I get no output at all. The page is still there with the css and the options
   across the top, but the text box that usually tells you your image was uploaded
   is completely empty. I tried uninstalling php-gd, and the “Filetype not supported”
   error came back. I reinstalled php-gd, and the box was empty again.
 * Please help!

 * I figured it out on my own. First off, if you get “Filetype not supported,” you
   need GD support for php. If you installed php from rpm, you need to install the
   php-gd rpm as well. If you installed from source, you need to recompile with 
   GD support.
    As far as the blank page after installing gd, I checked the httpd
   error log and saw this: PHP Fatal error: Allowed memory size of 8388608 bytes
   exhausted (tried to allocate 12000 bytes) I had to edit my /etc/php.ini file 
   and increase the memory_limit variable to 24M. Now it works!
