0.5.0 Changelog
***************
 - Added browse buttons for directory selection in options
 - fixed tk_colorChooser function problem for background and
   font colors.
 - cleaned up source - added more documentation
 - added ability to clear image hash items after html output
   was completed.  Otherwise descriptions would carry over to 
   next run.
 - removed ability to have images and html in different
   directories - caused too many problems with hard linking
   in the html output.

0.4.8 Changelog
***************
 - added a check for images when calling &create_images
 - added the ability to save and load settings
 - added a $thumbRoNum so you can set how many images you want
   displayed across in thumbnail view.

0.4.7 Changelog
***************
 - Fixed a minor bug in slideshow generation when descriptions
   are off.
 - Changed title of Help window to "$title - Help"
 - Finally got rid of hard coded .JPG image type - now you can 
   choose what extensions your images are.


0.4.6 Changelog
***************
 - Moved most settings into cascading menu off of the Options
   button.
 - Added a <Return> bind for the description bar which calls
   &next_file (same as what the Next button does).
 - Added underline => '#' values for menu items for quick
   navigation.
 - Removed "Beta" from name
 - Added options for no descriptions (scales and writes html)
   and for no html writing (simply scales images).
 - Added an error window sub
 - Added "Save Settings" (not enabled) and "Restore Defaults" 
   buttons on File menu.
 - Added "Cascade" to HTML Style options
 - Included 'start.pl' to the package.  From the camel book this
   destroys the annoying DOS window that pops up when running
   webpic.pl in a win32 system.  Not needed for *nix.
 - Fixed a small bug in win32 directory names and spaces.
