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

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();
        }
