Intervention Image Error Message

I'm trying to figure out how to install Intervention Image. I keep getting the error message Class 'Intervention\Image\ImageServiceProvider' not found

http://laravel.io/bin/jQkJ6 (Better markup)

1. Installed Intervention/Image by cding over into the correct file (command below)

C:\wamp\bin\php\php5.5.12>composer require intervention/image
Using version ~2.0 for intervention/image
./composer.json has been created
Loading composer repositories with package information
Updating dependencies (including require-dev)
  - Installing intervention/image (2.0.16)
    Downloading: 100% intervention/image suggests installing ext-imagick (to use Imagick based image p
rocessing.)
intervention/image suggests installing intervention/imagecache (Caching extensio
n for the Intervention Image library)
Writing lock file
Generating autoload files

1. I then followed the below Intervention/Image Laravel 4 installation guidelines http://image.intervention.io/getting_started/installation#laravel

2. I then got this error message "Class 'Intervention\Image\ImageServiceProvider' not found"

3. I then ran a composer dump-autoload command on the root of my app (root-> C:\wamp\www\laravel\register) Within 10 seconds I got "Generating autoload files"

4. I'm still getting the error message "Class 'Intervention\Image\ImageServiceProvider' not found"

5. I then ran a composer update --no-scripts command on the root of my app (root-> C:\wamp\www\laravel\register). The files were successfully created but I'm still getting the error message.

6. I then went back to my workbench directory of the verify package (C:\wamp\bin\php\php5.5.12) and ran a composer dump-autoload Within 10 seconds I got "Generating autoload files"

7. I then went back to the root directory of my app (C:\wamp\www\laravel\register) and ran a php artisan dump-autload command and I got this error message

C:\wamp\www\laravel\register>php artisan dump-autoload
{"error":{"type":"Symfony\\Component\\Debug\\Exception\\FatalErrorException","me
ssage":"Class 'Intervention\\Image\\ImageServiceProvider' not found","file":"C:\
\wamp\\www\\laravel\\register\\vendor\\laravel\\framework\\src\\Illuminate\\Foun
dation\\ProviderRepository.php","line":157}}

1. So I ran a composer dump-autoload command on the root directory of my app and got the below response. Within 10 seconds I got "Generating autoload files"

My question is, what am I doing wrong? How do I fix this problem?
