the watermark is useful only set "Protected view"?

when I set "protected view",address of one image will be like "http://www.aaa.com/50.jpg.html?p=*full-image"
but this address can not be quoted in Fourm or otherwhere.

I want protect my image with wartermark,and it can be quoted freely,how can I do ?

I have not found any way. However, we can change zenphoto so it does not use the '*' here. There will be a change in tonight's build that will provide a different URL for the full image.
