The intellectual property of your images is important, so we understand why you may want to prevent people from saving the images you place on your website.
Prevent visitors from saving artwork images
Warning: Unfortunately, it is impossible to make images 100% secure from being downloaded, but you can enable this functionality to make it more difficult.
In your CMS, go to Settings > Settings > Artworks > enable Prevent visitors from saving artworks.
Do note: While it may be tempting to disable the right-click menu on your website, making it harder to download images can also frustrates your website visitors. The right-click menu has many useful functions that allow options and quicker forms of navigation. Visitors may even have custom functionality added to their right-click menu which you would be preventing them from using whilst browsing your website.
