Answer 1

On Heroku, GD is a "shared" extension that you can enable in composer.json. No custom buildpack required, just add the ext-gd line in your composer.json:

{
  "require": {
    "ext-gd": "*"
  }
}

Answer 2

You'll need to use a custom buildpack with imagick or gd compiled in.

I don't believe the latest version of heroku's official PHP buildpack has support for this, but I've created my own buildpacks for this too.

See https://github.com/winglian/heroku-buildpack-php (This version is built on 5.4.11 using PHP-FPM, but you can choose an older tagged branch for 5.3 support using mod_php.)
