Bulk Watermark Photographs – FastStone Image Viewer

by Ka Edong on May 1, 2008

Last night, it took me almost an hour to search for an easy way to put watermarks on my tons of photos at http://photos.edongskey.com .

In particular, I was looking for an easy way to do a Bulk Watermark for photos.  There are many softwares that can do this. But as usual, I was looking for the one that was free and did not have any nags. I didn’t want trial versions that had additional un-wanted watermarks of the software name. I didn’t want trial versions that had limited functionality. I didn’t want free software that could possibly have some trojans in them.

And I found FastStone Image Viewer! It works perfectly for my purposes. I am able to add watermarks on hundreds of photos.

Here’s how I add watermarks for photos that are *already* uploaded on my webserver.

a.) Download the photos from webserver unto my hard drive using my FTP client. I use FileZilla because of the same criteria I used for Faststone (Free, not trial nags, no trojans, full functionality).

b.) Add watermark using FastStone. Select Photos > F3 (Bulk Convert) >  Advanced Options > Text … (then set your watermark).

c.) Save the watermarked images on my hard drive.

d.) Upload watermarked images to my webserver using FTP

I chose to un-check “rename” when I Bulk Convert. This is so that the exact names of the photos are used when I upload the watermarked photos — this preserves all links to the old photos.

Also, I un-check the “Keep original Date / Time attributes”. Thus, after watermarking, the image’s date modified is changed to today. This helps me keep track of which of the 1 thousand photos on my server are already watermarked (Answer: the ones with dates modified lately).

Hope that’s useful.
