I was checking out the screenshots and wound up in the source directory. There were a lot of images. I didn't want to keep clicking back and forth between the source directory and the links so, I made a simple slideshow that scrapes the directory for image links.

instructions to start
1)download and unzip the above link to your documents directory (or any directory that is not the desktop. Otherwise, your system will complain about permissions with connecting to quaketastic remotely and will not honor permissions)
2)either open the standalone player I included, click "file" and select Quaketastic_Screens.swf or right click Quaketastic_Screens.swf and "open with" the provided standalone player (or any other standalone player you may have or need to download if you aren't on windows)
How to use:
Left Arrow Key = previous image
Right Arrow Key = next image
How it works (internally...if you want to know):
1) The entire directory is scraped of all image paths and those paths are pushed into an array
2) The first index of the array is automatically downloaded, pushed to the lib and displayed
3)every time you press right or left the library is checked. If the image exists it is displayed. If it doesn't exist it is downloaded, pushed to the library and displayed.
Basically the images are downloaded as you first request them. Past that it is just traversing the library. I'm telling you this because, if you have limited bandwidth this is potentially a terrible solution for you to view the images with.
I may make this better one day. It pretty much has zero features beyond previous/next image.
