+## Apache index image viewer
+Webserver don't by default provide a way to view quicklooks of images besides 
+by clicking on each image to open it.
 
+ImageBrowser will provide a very basic image view for all image file types
+contained in the same directory location as the web page. 
 
+Requirements:
+* The directory must be using Apache `mod_autoindex` as well as the `Indexes`
+  option configured in the target directory.
+* The webpage must not be named `index.html` or any other configured auto index
+  filename. The default page name is `images.html`.
   
+Supported image types include all types supported by the HTML `img` tag, which
+currently includes jpg, jpeg, png, gif, and bmp.
