How to download dam images from sightly code?

[Ronnie09]

Hi,

I tried the code mentioned below.

<a href="/content/dam/wknd/images/sample.jpg" download>
  <img src="/content/dam/wknd/images/sample.jpg" alt="sample" width="104" height="142">
</a>

 This piece of code opens the image in a new tab, it doesn't download the image to my system.

How to achieve this functionality.

you have to look for Content-Disposition header to achieve that

EXAMPLE, That file is send with these headers:

Content-Type: application/force-download
Content-Disposition: attachment; filename=bike_chase-wallpaper-2560x1600.jpg

You mean I have to write servlet and send these data through that servlet.... Content-Type: application/force-download

Content-Disposition: attachment; filename

This code I tried.. it is downloading the image but it shows, image format not supported

try {
            ResourceResolver resourceResolver = request.getResourceResolver();

            Resource assetResource = resourceResolver.getResource("/content/dam/wknd-shared/en/contributors/ayo-ogunseinde-237739.jpg");

            Set<Resource> assetSet = new HashSet<>();
            assetSet.add(assetResource);

            response.setContentType("application/force-download");
            response.setHeader("Content-Disposition", "attachment; filename=ayo-ogunseinde-237739.jpg");
            assetDownloadService.assetDownload(assetResource, assetSet, true, false, false, null, null, "ayo-ogunseinde-237739.jpg", StringUtils.EMPTY, response.getOutputStream());
        } catch (Exception e) {
            e.printStackTrace();
        }

you need to write a filter which add those headers when images are requested.

@arunpatidar  this code looks valid, 

<a href="/content/dam/wknd/images/sample.jpg" download>

Why doesn't this work?

This opens image in new tab

This depends on browser settings as well.

Please try 

There is an OSGi Configuration in Felix console named "Apache Sling Content

Disposition Filter" which controls Content Disposition for different mime types based on the path
