+# Image anonymizer
+
+**Image anonymizer** is a frontend program for some tools that work with images.
+
+The program makes a **PNG** copy of the original image; the copy is optimized and **all metadata is removed**.

+
+## Install
+
+### Requirements
+
+* **[GNU bash](https://www.gnu.org/software/bash/)** is the **GNU Project**'s shell—the **Bourne Again SHell**.
+* **[Zenity](https://help.gnome.org/users/zenity/)** is a rewrite of **gdialog**, the **GNOME** port of dialog which allows you to display dialog boxes from the commandline and shell scripts.
+* **[ImageMagick](https://imagemagick.org/)** is a suite of programs for creating, editing, compositing or converting digital images. It can read and write images in a variety of formats.
+* **[Exiftool](https://www.exiftool.org/)** is a platform-independent **Perl library** plus a command-line application for reading, writing and editing meta information in a wide variety of files.
+* **[OptiPNG](http://optipng.sourceforge.net/)** is a **PNG optimizer** that recompresses image files to a smaller size, without losing any information.
+
+### Get the code
+
+You can use **git**.
+
+    git clone https://git.lattuga.net/netico/code-library.git
+
+and then look for the script **image-anonymizer.sh**.
+
