Automatic Image Gallery
Posted: Mon Sep 12, 2011 4:19 am
Hi
I have been trying to make the automatic image gallery work for some time now and i am unable to find what is wrong
I hope someone can help, here is my code:
does'nt work. The code does create the the thumbs folder.
At this point(code below) the Betterphp video outputs the blue rectangles with the file name written in them, mine outputs nothing.
However i don't see anything wrong with this part of the code

All i get when i run this code is the blue rectangles with the file name written in them, it seems the the thumbnail partdoes'nt work. The code does create the the thumbs folder.
At this point(code below) the Betterphp video outputs the blue rectangles with the file name written in them, mine outputs nothing.
However i don't see anything wrong with this part of the code
if(is_dir('./thumbs')===false){
mkdir('./thumbs', 0744);
}
$images = glob('*.{jpg,jpeg,gif,png}',GLOB_BRACE);
?>

foreach($images as $image) {
if(file_exists("./thumbs/{$image}")) {
echo "<a href=\"{$image}\"><img scr=\"thumbs/{$image}\" alt=\"{$image}\" /></a>";
}else{
echo "<a href=\"{$image}\"><img scr=\"?img={$image}\" alt=\"{$image}\" /></a>";

Thank you
