I am using some old sharware called "highslide" it has nice buttons for left/right/close, and click to show full image, but for the life of me, I can't seem to write/configure the thumbs.php file? Highslide was written to call a single file. The purpose of the postings are news and event releases with photos. I manually upload new folders inside a ongoing/updated "gallery" directory, that I have also created. I make a folder inside the new date_xxx/name_xxx folder with full size images, and one called thumbs. The .php script, needs to look for the thumbs to display them, then have the relative paths for the full images when clicked.
