//READ FOLDER
$folderRoot = 'images/art_shows';
$folder=opendir($folderRoot);
while ($file = readdir($folder))
$image_names[count($image_names)] = $folderRoot . $file;
closedir($folder);
I added a variable $folderRoot and prepended it to the value of file.
readdir() is a great function, but only returns the name of the file,
not it's location, so you need to prepend the location relative to the
current script in order for the files to be called anywhere else.
Hopefully that'll work.
