NOTE: The original post was a request for a simple, text based watermark which has been implemented. This thread will continue to be the place to vote for image based watermarks.

Looks like the watermark feature had been requested for years and yet...we are still waiting for the improved version of LR mobile.
I started using the LR mobile recently. It is convenient but I feel sort of 'lack of something' without the watermarks.
I hope the watermarks feature request will be considered by Adobe!
Adobe, you are great and fantastic, always pushing the boundaries into new horizons of software genius, making it fun to use and very high quality. As a company that seems to take growth and customer satisfaction seriously, I bid you to consider very seriously this thread, and the other hundred out there like it: PLEASE ADD A WATERMARK FEATURE TO LIGHTROOM MOBILE! PLEASE! WITH A CHERRY ON TOP.
It doesn't have to be a full feature watermark like on Lightroom Desktop, however, a text watermark is essential to anyone who takes protecting their intellectual property seriously. So do that.
In my mind, it would be perfect if when you shared, or saved to gallery, it would ask if you wanted to watermark your photo. If you said yes, it would take you to a screen where you could do that, if you said no, you'd be on your way.
I plead with you from the bottom of my heart, PLEASE ADD A WATERMARK FEATURE TO LIGHTROOM MOBILE!
Lightroom mobile should at least have the ability to add pretty existing watermarks to the pictures you save. Without this option, one can't really share ones pictures with anyone. This practically makes the app useless in spite of all the other awesome features and convenience.
It would be great to be able to select preset watermarks when using the LR mobile app. The need to sync files in the desktop catalog to set a watermark and re-sync them again in your mobile would be very inconvenient and would make LR mobile app ineffective when traveling.
I love lightroom mobile but I rarely post my photos from it because of the lack of copyright ability. I love how streamlined the app is but feel as if I cannot utilize it to its potential because of not being able to protect my photos. I'd probably wouldn't be using my laptop that much anymore if I had that feature. I don't know the coding involved that would allow such a feature to be used but I would love to see this implemented or created because it would make the app stand apart from regular photo editors. Not only can you edit professional photos on your ipad, but you can also upload it too. This would be awesome to see happen, thanks!
Why does the watermark application have to reside on the export module? why can't it rest on any picture in the library like a layer so that when you send it to mobile, or export it external to Lightroom, it already has the watermark and and is then applied permanently? I think putting it on the export module is a mistake.
