batch watermark photos

[ic0n]

hi guys i am on mac osx and need to batch watermark lots of photos about 800 before uploading to web

i have tryed all the work arounds in photoshop and find them to well suck and not work right

if there is a really good tutorial that works i will be happy to do it but is there a plug in for photoshop or lightroom that will do this

or a 3rd party program that will do this for free i just want to put text over the photo so people carnt go print them.

thanks

Take a look at: http://www.imagemagick.org/script/index.php

Imagemagick contains a set of binaries which you can drive from the command line to do this sort of batch processing which makes this sort of thing a breeze if you are reasonably happy using the CLI.

There is reasonable documentation on that site how to use it, but in summary, what I do is create a watermark image, lets say "myWatermark.gif", and then use the command:

composite -dissolve 50 -mavity southeast -geometry +10+10 myWatermark.gif inputImage.jpg outputImage.jpg

which "dissolves" (or watermarks) myWatermark.jpg into the file outputImage.jpg, putting it on the bottom right of the image, 10 pixels from the edge.
I run it on Linux where I can readily script it to drill through a directory structure modifying all the files automagically (you can specificy inputImage.jpg and outputImage.jpg to be the same to modify the files insitu). I'm not famililar with macOS but I assume you can script up something similar?

More or less what I do for such batch jobs. ALthough for watermarking I use the 20th century digital version - the EXIF data. Much neater than distorting the image data.

You could also do it in Picasa, very easy to do.
