This is very similar to the automatic version
here, except that you manually initiate the download.
Due to the instability of this page with iRex's html viewer, you will need to install my latest port of
FBReader
When you select the program, it will check to see if it's updated today. If it has not, it will automatically open the connection manager, and download the day's comics. When finished, it will open FBReader and display the comic page. If it has already downloaded, it will simply open FBReader with the comics.
You can unzip the program into any directory you'd like.
Edit: The attachment has been updated to allow directories with spaces
Edit 2: If you are having prolbems viewing all of the images and have unbricking support, see this post
