How to apply an oblique watermark on a large number of images?

Question

Watermark

There are a large number of photos on the working site, and a watermark has already been applied to them - but it is large and quite simple - our photos are stolen, copyright erased and passed off as their own ...
I want to impose another watermark - but as in the photo (it's just sample)

How to do it in batch on the server?
It is desirable that the text be gradient or otherwise colored, IMHO so it will be more difficult to erase it by mask in a photo editor

Answer 1

ImageMagick

Answer 2

Use the functionality of IRFANVIEW GRAPHIC VIEWER
There is batch processing of graphic files, including watermark overlay.
