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:

dat_srq_set_lw
dat_srq_set_lw(3DAT) Direct Access Transport Library Functions dat_srq_set_lw(3DAT)
NAME
dat_srq_set_lw - set low watermark on shared receive queue
SYNOPSIS
cc [ flag... ] file... -ldat [ library... ]
#include <dat/udat.h>
DAT_RETURN
dat_srq_set_lw (
IN DAT_SRQ_HANDLE srq_handle,
IN DAT_COUNT low_watermark
)
PARAMETERS
srq_handle A handle for an instance of a Shared Receive Queue.
low_watermark The low watermark for the number of Recv buffers on SRQ.
DESCRIPTION
The dat_srq_set_lw() function sets the low watermark value for the SRQ and arms the SRQ for generating an asynchronous event for the low
watermark. An asynchronous event will be generated when the number of buffers on the SRQ is below the low watermark for the first time.
This can occur during the current call or when an associated EP takes a buffer from the SRQ.
The asynchronous event will be generated only once per setting of the low watermark. Once an event is generated, no new asynchronous events
for the number of buffers inthe SRQ below the specified value will be generated until the SRQ is again set for the Low Watermark. If the
Consumer is again interested in the event, the Consumer should set the low watermark again.
RETURN VALUES
DAT_SUCCESS
The operation was successful.
DAT_INVALID_HANDLE
The srq_handle argument is an invalid DAT handle.
DAT_INVALID_PARAMETER
Invalid parameter; the value of low_watermark is exceeds the value of max_recv_dtos.
DAT_MODEL_NOT_SUPPORTED
The requested Model was not supported by the Provider. The Provider does not support SRQ Low Watermark.
USAGE
Upon receiving the asynchronous event for the SRQ low watermark, the Consumer can replenish Recv buffers on the SRQ or take any other
action that is appropriate.
Regardless of whether an asynchronous event for the low watermark has been generated, this operation will set the generation of an asyn-
chronous event with the Consumer-provided low watermark value. If the new low watermark value is below the current number of free Receive
DTOs posted to the SRQ, an asynchronous event will be generated immediately. Otherwise the old low watermark value is simply replaced with
the new one.
