How to view images from local directories in play scala project

Question

I am newbie to Play scala framework,in my project I have a functionality of uploading a image and showing a uploaded image into view page.I have stored the uploaded images into my system's local folder and passed the images path into my view page,but it doesn't show the images. I have passed the image stored location path as imagepath and used the below code to view the image.

<img [email protected](imagepath) class="responsive" >

Note: If I stored the images in projectname/public/images project directory the images are showing in view page. please help me to resolve this issue.

You need to implement an action yourself. As I answered in Play Framework: Handling dynamic created files (images) in PRODUCTION mode

Here's the steps First in your routes file, add something like this:

GET /user/images/:name controllers.Application.imageAt(name:String)

And write a simple file reader in action imageAt which return the file in stream. Again my sample is in Java but you should archive the same using Scala

    File imageFile = new File(ReportFileHelper.getImagePath());
    if (imageFile.exists()) {
    //resource type such as image+png, image+jpg
        String resourceType = "image+"+imageName.substring(imageName.length()-3);
        return ok(new FileInputStream(imageFile)).as(resourceType);
    } else {
        return notFound(imageFile.getAbsoluteFile());
    }

After that, the images is reachable via revers router:

 <img [email protected](imageName)>

Or directly via url

 <img src="/user/images/imageName">
