If you want to watermark an image everytime that wget fetches it , you have to separate each wget call per url in a loop in a shell script. Then everytime wget successfully downloaded an image, the script will call another tool to add watermark to the image. The problem arises with how you will save the images to your local directories.
With respect to watermarking, there are lots of tutorials on the web on how to do it like in these pages:

WMGRABIMGAE(1) General Commands Manual WMGRABIMGAE(1)
NAME
WMGRABIMGAE - Dockable WWW Image monitor.
SYNOPSIS
wmGrabImage [-h] [-display <Display>] -url <Image URL> [-http <URL>] [-c] [-delay <Time>]
DESCRIPTION
wmGrabImage is a WindowMaker DockApp that maintains a small thumbnail copy of your favorite image from the WWW. The image to monitor is
specified via the "-url <Image URL>" command-line option and it gets updated approximately every 5 minutes. The update interval can be
overridden via the "-delay <Time>" command-line option (Time is in seconds).
Each of the three mouse buttons can be double clicked with the following effects;
Left Mouse:
Brings up the full-sized image in xv.
Middle Mouse:
Sends a URL (specified via the -http <URL> command-line option) to an already running netscape process or in a new netscape process
if there arent any running.
Right Mouse:
Updates the image immediately.
OPTIONS
-h Display list of command-line options.
-display [display]
Use an alternate X Display.
-url <Image URL>
The URL of the WWW image to monitor.
-http <URL>
The URL to send to netscape via a Middle double click.
-c Center the image vertically within the icon.
-delay <Time>
The time between updates. The default is about 5 minutes.
FILES
The original sized image and the thumbnail XPM image are both stored in ~/.wmGrabImage/ which gets created if it doesnt already exist.
SEE ALSO
wget and the ImageMagick convert utility.
BUGS
Who knows? -- its still Beta though. (Let me know if you find any). Oldish versions of the ImageMagick convert utility have a memory leak
-- if you have that problem, upgrade to the latest version.
