Wordpress: Filetype not supported. Thumbnail not created
Image upload Resize in Wordpress….
I notice a fair number of people on google not finding this solution to a problem that is pretty easy to fix once you know what you have to do. Windows users should check out this page, as I have not tested the window version of much anything in years. Linux users and Debian specific (but php is php) can look for a file called “php.ini” check for it at “/etc/php4/apache/php.ini”. That will change depending on your setup and what php version you are running. Next add the line “extension=gd2.so” and “extenstion=gd.so” some place in that file with all the other extensions. Older version of the php4 config file will have some like “extension=php_gd.dll” and you should think about a upgrade if you have that. Last make sure you have the packages “php4-gd libgd2 libgd2-xpm”. You might not need all 3 packages and both extensions, but this should make sure you get your thumbnail resize working in Wordpress.
