PHP - Resize image on upload AND keep original - php

Question

I'm creating a site using Laravel 4, which allows an admin to upload a large number of images at a time. Currently, I'm able to do just that, where each image is given its own unique ID and put into its own folder named with the same ID.
The problem is that I need the application to also upload a second, resized (smaller) version of the image along with the original. I learned that you must resize an image on the client side, so I'm not sure how I would go about saving the original image, as well as smaller version. The smaller image should be named using the same ID, with some sort of identifier like "-smaller" at the end of the name.
Here's my current front end;
{{ Form::open(array('url' => 'imageUpload', 'files' => true, 'method' => 'post'))}}
<div class="form-group">
<label for="fileToUpload" class="col-sm-2 control-label">Choose All Images</label>
</br>
{{ Form::file('images[]', ['multiple' => true]) }}
</div>
<div class="col-sm-offset-2 col-sm-10">
{{ Form::submit('Add Photos', ['class' => 'btn btn-large btn-primary openbutton'])}}
<!--<button type="submit" class="btn btn-default">Sign in</button> -->
</div>
{{ Form::close() }}
And here's my controller;
$files = Input::file('images');
foreach($files as $file) {
$rules = array(
'file' => 'required|mimes:png,gif,jpeg,txt,pdf,doc,rtf|max:9999999999'
);
$validator = \Validator::make(array('file'=> $file), $rules);
if($validator->passes()){
$id = Str::random(14);
$id = $race . "-" . $id;
$destinationPath = 'raceImages/' . $id;
//$filename = $id;
$filename = $file->getClientOriginalName();
$mime_type = $file->getMimeType();
$extension = $file->getClientOriginalExtension();
$upload_success = $file->move($destinationPath, $id);
);
} else {
return Redirect::back()->with('error', 'I only accept images.');
}
}

This is how I resolved the same problem in my app:
Install this package: https://github.com/Intervention/image
Use this code:
$createnew = new Yourmodelname;
$avatar = Input::file('pic_path');
if (isset($avatar)) { //will process the code only if an image was properly pointed in the form
$image = Input::file('pic_path');
var_dump($image->getRealPath()); // just for error tracking
$filename = $image->getClientOriginalName();
if (Image::make($image->getRealPath())->save('foldername/yourprefix_' . $LastInsertId . '_' . $filename)) { } // foldername is related to your public folder
if (Image::make($image->getRealPath())->widen(200)->save('foldername/thumbs/thumb_yourprefix_' . $LastInsertId . '_' . $filename)) {
}
$createnew->pic_path = 'event_poster_' . $LastInsertId . '_' . $filename;
$createnew->pic_thumb = 'event_poster_thumb_' . $LastInsertId . '_' . $filename;
$createnew->save();
}
Now you have two files: one original (no changes) and a thumbnail scaled proportionally to width 280.
Other resize options you can find in the Intervention docs.
