If you upload your images online on social sites, then you will always be concerned about protecting your pictures copyright. You can easily protect your pictures copyright by digital watermarking your images with your name or with a custom watermark that has a logo / symbol / signature of you or your company.
According to Wikipedia
Digital watermarking is the process of possibly irreversibly embedding information into a digital signal. The signal may be audio, pictures or video, for example. If the signal is copied, then the information is also carried in the copy.
PicMarkr is a service that allows you to freely add custom watermark to your images. You can watermark you images for free in three steps :
1> Upload your images – You can either import the image/s from photo sharing social sites like Flickr, Picasa or Facebook or upload an image from your computer. Those of you who are not comfortable sharing your personal password of social networking sites, can download the image to your system and then can use the upload from computer feature of PicMarkr.
2> Apply Watermark – There are three types of watermarking options: Text, Image or Tiled. Select the one that best suits your need.
3> Get Watermarked images – The uploaded images will be watermarked immediately and you’ll be able to upload it directly to social photo sharing sites or save it to your computer.
While uploading the images you also will have an option to resize the uploaded images.
You do not have to download anything to your system, no setting changes or no configuration required and it PicMarkr supports batch image processing.
