Trying to work out what server modules (*nix) I need the hosting admin to install to have green across the board.

Specifically we currently have No for the following:

  • CAPTCHAs feature and watermarking in Image Gallery
  • JPEG Image Resising User GD (or GD 2)

See result of running the wizard below.

Thanks Brendan

OK, I checked and managed to work out with the hosting provider what needed to be done. Basically with the PHP config, we needed the following flags set:

For CAPTCHA support:


For JPEG Image Resizing support (path different depending on server setup):


If you install Expression Engine and you doesn't need a Captcha feature (to avoid spams), or no need to resize jpeg picture, it will works fine.

But if you really need a system similar to avoid spams, exists a lot of addons about this.
