+# batchWaterMarking : a simple way to watermark all your pictures in one line
+
+This repository contains the last version of my personal watermarking script. 
+
+This script simply aims at adding an unobtrusive watermark to all images of an input folder and copy final images in an output folder.
+The watermark is added with transparency effect in order to keep the image quality. 
+
+The script should recognize all kinds of image formats, and correctly handle filenames with spaces and (most of) unusual characters.
+In addition, the script is designed to automatically recognize whether your image is in portrait or lanscape mode. The watermark is put in a different corner to better visual results. 
+
+The use of this script is pretty straightforward : 
+```Bash
+$ waterMark in_folder out_folder watermark_image
+```
+
+where :
+- in_folder contains your input images
+- out_folder will contain all new images
+- watermark_image is the watermark you want to set on the image
+
+The script also resize images in order to fit with [Piwigo](http://fr.piwigo.org/)'s default settings. (1024x768). This option should be set as optional soon.
+
+## Installation
+
+The only prerequisite to use this script is imagemagick : 
+```Bash
+$ apt-get install imagemagick
+```
+
+You do not need to install this script in any way. 
+You can use it from anywhere as long as you use __absolute paths!__
+
+A simple way to use waterMark from anywhere is to add it to your ~/bin folder; and give the script execution rights.
+```Bash
+$ chmod +x ~/bin/waterMark
+```
+This way, you will be able to run it directly in your terminal. 
+
+## Next steps
+
+Some more options should be added soon:
+- Insert some contrast calculation in order to choose the best color from two different watermarks. This way, the watermark would always be visible
+- Dynamically changechange the size of the watermark to avoid resizing input images
+- Windows support ? ? ?
+- Python version to avoid ugly bash ? 
+
+Any idea is welcome
