Gimp-Forum.net

I need to watermark my photos since I've begun putting them up on the web. 

 Gimp seems to be capable of watermarking but the only thread I found was a couple of years since the last comment and it seemed to talk about one by one.  I think batch processing is very necessary.  My photos generally come in chunks of around 100 at least for instance.   And then there's thousands already on hand not yet watermarked.

So is it possible to watermark with Gimp?  And if it is can it be batched?

Maybe this can help you :

Batch with bimp :

For Gimp, unless you write a script, then it is BIMP see: link in previous post. For Gimp 2.8 (Windows) you need version 1.8

Thanks very much.  Good news.
