The Protection addon disables image right clicking in both slider and lightbox views to prevent visitors from downloading your images.
Using this addon is easy – all you have to do is activate it!
After activation, the protection addon will be automatically enabled for all of your newly created sliders. Existing sliders should be updated to have image protection applied.
You can turn off image protection on an individual slider basis by unchecking the “Enable Image Protection” option under the Misc tab in the slider management box.
