 Image Viewer Tool
 =================
 
-Placeholder for image viewer help
+Description
+-----------
+
+This tool loads image files and displays them as 2D (x-y coordinate against 
+counts per pixel). The plot can then can be saved, printed, and copied. The 
+plot can also be resized by dragging the corner of the panel.
+
+Supported image formats are png, bmp, gif, or jpg. (There is currently a bug in 
+the tif loader)
+
+.. ZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZZ
+
+How To
+------
+
+1. Select 'Image Viewer' under the 'Tool' menu in the menubar.
+
+2. Select a file type from the drop-box at the bottom of the file dialog panel, 
+choose a file of interest, and then click the 'Open' button (see the 
+picture below).
+
+.. image:: load_image.bmp
+
+3. If the loading is successful, the image will be displayed. The file name 
+will be shown in the title bar (see the picture below).
+
+4. Some options such as saving, printing, and copying are available from the 
+menubar, or in the context-menu (by right-clicking anywhere in the plot).
+
+.. image:: pic_plot.bmp
+
+5. If the image is taken from a 2D detector, it can be converted into 2D data 
+where the z values are computed as 
+
+z = (0.299 x R) + (0.587 x G) + (0.114 x B)
+
+unless the picture file is formatted as 8-bit grey-scale tif.
+
+In the "Convert to Data" dialog, set the parameters relevant to your data and 
+then click the OK button.
