Serving PHP image resource as response in Laravel

Question

I am developing a web application. In my application, I need to work with some images and display it on the browser. But I am not saving the image as a file and access the file from the path. I am not doing it for some reason. Instead, I am creating an image resource from some kind of byte data and then serving it.

This is my code in the controller.

function serveS3Image(Request $request)
{
    $image_data = Storage::disk('s3')->get($request->get('identifier'));
    $data = imagecreatefromstring($image_data);
    header('Content-Type: image/png');
    imagepng($data);
}

When I access the action from the browser, it is displaying me correct image. But I want to do it in more Laravel way. Something like this:

function serveS3Image()
{
     return Response::ImageResource($data);
}

How can I return the PHP image resource?

Finally, I have got the solution based on some answers. I just needed to return like this.

return response(Storage::disk('s3')->get($request->get('identifier')))->header('Content-Type', 'image/png');

In the response, I passed image data, not the file path. Then I set the content type in the header. Thanks eveyone.

I found same question on Laracast like your. Look at this thread. I hope it will help to you.

EDIT: add code from laracast

public function downloadAsset($id)
{
    $asset = Asset::find($id);
    $assetPath = Storage::disk('s3')->url($asset->filename);

    header("Cache-Control: public");
    header("Content-Description: File Transfer");
    header("Content-Disposition: attachment; filename=" . basename($assetPath));
    header("Content-Type: " . $asset->mime);

    return readfile($assetPath);
}

Thanks! Actually, it wasn't me who downvoted (some guys are not that patient and link-only answers tend to get downvotes..)

Sometimes I do not see the point of copying an answer from another site if it can be viewed there with other answers.

Well, the main point is accessability. Starting from one doesn't go to a third-party site to get the answer (especially in difficult cases when they're searching for an answer and some answers are not relevant) and ending with cases when a link gets broken and the answer becomes a "here's a nice solution: [broken link]" thing (quite discouraging, right?)

I agree with you.

https://laravel.com/docs/5.5/responses#file-responses

The file method may be used to display a file, such as an image or PDF, directly in the user's browser instead of initiating a download.

This method accepts the path to the file as its first argument and an array of headers as its second argument:

return response()->file($pathToFile);

return response()->file($pathToFile, $headers);

I am not saving the image as a file. I am getting that image data from some kind of api.

Dezigo Over a year ago

have you tried? $img = Image::make($contentOfTheImage )); return $img->response('png', 70);
