PhotoStamper is a very simple application that allows you to stamp your photos with title, place, text, GPS location and date at the bottom of the image. The program allows you to select exactly the categories you want to show on your image and you can also customize the font size, but not the color or font type from the Options menu.
Sadly, the stamp won't be added to the image itself, but a small white portion will be added to the bottom of the selected image. Before saving the image with the changes, you can preview what it will look like and then you can save it in the desired location in multiple formats. You also will be able able to send the image by email directly from the program and write a small message. It would be great if you could decide where you wish to stamp the data and customize other important options mentioned above.
Roughly speaking, PhotoStamper is just a simple application to stamp data to your images, but you will surely find some better applications out there.
