I am using DW if that helps
I can't think of anything that hurts more. DW--more accurately named "Nightmare Maker"--produces some of the worst code possible in every language it works with.
Anyway, this really has nothing to do with DrunkWalker.
You just need to use some database tool to add the column to your table.
And then *YOU* need to decide what to store in that column.
If all your images will be in the same directory, then I'd recommend just storing the name of the image and nothing more. That way, if you move or rename the directory, your database contents don't need to be changed.
If you are using, say, a two-level sytem (say you have /images/fullsize/butterfly.jpg and /images/thumbnail/butterfly.jpg ), then again store only the last part of the path. Just "fullsize/butterfly.jpg" or "thumbnail/butterfly.jpg". Again, that means you could later move the "images" master directory (or rename it) and the DB contents don't change. Do NOT store the full path to the images.
I do have to ask: What do you mean by "dynamic table"??
