"Tagging Tool" is an easy-to-use open source software that lets users tag their images with ease. With a simplistic graphical interface, it simplifies the process of categorizing and organizing images.
One of the great things about Image Tagger is that it allows you to select multiple images at once, and then batch set all desired tags for them. This can save a ton of time if you need to tag many photos at once.
It's important to note that Image Tagger is not an image library program, like iPhoto or Picassa. Rather, it functions solely as a tool to tag images prior to processing by other software.
Some key features of Image Tagger include its true cross platform library, which means it's not tied to a single application for tagging/viewing. Additionally, there's no chance of database corruption losing all of your images/metadata. Even in the worst case scenario of a corrupt file, only data for that file will be lost.
Overall, if you need a simple yet reliable tool for tagging your images, Image Tagger is definitely worth checking out.
