Using the Archive
You can use the arrow keys on your keyboard to navigate the thumbnails and the screenshots. Pressing the up key will move to the previous gallery (or Homepage) and using the right/left arrow keys will cycle through the images.
The images displayed here are just used as previews for the gallery. The actual resources are in the included zip file, that contains the entire archive, including all files (bmp, psd, vpt, fpt etc)
