Description: ** update ** I fixed a small typo in the thumbnail sub and a small error in my html tags. djw - June 27/01. Sorry if the code format is off a bit, I was testing out Komodo as an editor.

You can find the latest and greatest version at my site. You can find win32 binaries of Tk as well as html examples of output.

WebPic Beta
================================

What it does:

Read in a directory of digital cam pics, scale them to whatever percentage you want(in multiples of 10), provide an option for descriptions, and write an html page for viewing pictures.


0.3.6 Changelog
***************
- removed all hard coded paths/names - added to options
- added html style types - cascade and thumbnails
- added some defaults for the options window
- added clear and cancel buttons to options
- added a help menu (this file) - will include more later

0.3.5 Changelog
***************
- finished options window
- added a new dir location option
- Added a scale value
- finished html output default

0.3.0 Changelog
***************
- Added GUI - too much to name, first real version


To Do:
  • Complete keyboard shortcuts and frame focus stuff for speedy use
  • No GUI option. eg: "# webpic.pl -nogui -scale 20% -dir /var/www/images -newdir pr0n" etc
  • add the option to not have descriptions (no gui mode only?)
  • thinking about a slideshow html style
  • Need to add html bg and font colors to the option
