The licensing you attribute to your uploaded content gives you control over how others are able (or, not able) to use it. You can learn more about the different licensing options here.
While the aim of attributing a stricter license to your items is to discourage others from downloading it, unfortunately there will always be people out there who may disregard this & attempt to download your content anyways.
The only way to entirely prevent this is to remove your content from public view & make it private.
Below are some other ways to better control who is able to download your content:
- Limit access to your ‘original image’.*
- Limit the size of the image you want others to have access to.
*Note: Original downloading for videos is only available to the member who uploaded it anyway.
