To slice an image in paint shop pro, go to
file>>export>>image slicer. Select the grid tool
at the top of the window, and decide on how many columns and
rows you will have (this will determine the number of sliced
images). You can uncheck the optimization option if you want.
Now go to save as, and save the .htm file under your preferred
folder. This will also save your diced images in that folder
as well.
When
uploading, be sure to upload ALL image files and the .htm file
to the same directory. Now you can open your .htm file in a website
building program like Frontpage or Dreamweaver, and edit it to
your liking.
