Thumbnails and original image

When you download the image the original image is downloaded.
When you click on the name the image original image is shown in the new tab.

Display of non-open formats of images

heif and heic are two image format (known to Avni team) that cannot be displayed in the browser and cannot be processed by standard libraries to generate thumbnails. These image formats are known to come from some Samsung devices.

Due to this, the thumbnails are not visible in the media viewer web app. But you can only download the full size images for the same.

Currently the users can upload standard images by turning of this feature in Samsung. There are two settings that need to be changed as described in this short video.
