PhotoPageGenerator v2.0 - Visual Basic Source Code

This is an old, outdated version of the program for archiving purposes only. To see the latest version, please follow the link below:
Photo Page Generator v2.3

Back to: Main Programming Page

This is a program I wrote to generate some html code to automate the making of photo pages. It will read a directory to get all of the images, write the html code to put them in thumbnails, and generate a webpage for each photo (with navigation links and a handy-dandy javascript that dynamically resizes the image to fit the window). You can even generate different galleries for the images in a directory. There is also a readme file included in the zip archive with detailed directions on how to use the program. In general, this version has more functionality than the original version, but for the time being has lost the ability to generate a drop-down box for a slideshow. Note that the code it generates is to work with the format of my Photo Pages, but you could easily edit the code to make it fit whatever format you wanted. This program uses a module written by David Crowell to read in the image sizes.

Form1:
Form1 Screenshot
'Instructions:
'1. Make sure all input boxes are set up properly.  It's usually easiest to do that from
'the VB editor, and save it, so that in case there are any bugs, you don't have to
'input them all over again.
'
'2. Hit the Read Graphics Directory button.  This will output text into the "File List"
'box of the form needed for the program.
'
'3. Optional - copy and paste that text into a separate text file for archiving.  You can
'rearrange the order of pictures here, add the captions for the index page, or modify the
'captions for the photo pages.
'
'4. Optional - Copy and paste the list from the separate text file into the "File List" box
'
'5. Hit the "Create Page for Each Photo..." box.  This will create the individual html
'photo pages.  It will also output the necessary html code for the index page into the
'"HTML Output to Copy and Paste" box.  Copy and paste that code into the index page.
