[RESOLVED] Thumbnail creation...question

[davieboy]

hey folks

is it possible to do the following:

have a page that will create thumbnails for all the image files in a directory?

ie it takes the folder name and autogenerates the thumbnails?

thank you for that link it is very usefull

i dont think it is what i meant though.

what i mean is if i have a php code that i define the source file ie domain.com/images/
can the page automatically show me thumbmails of all the images in that file.
In other words having one page as an index page to show the images in the directory

ok i have uploaded it but having the following problems

could not open directory!

	/* INITIALISATION */

// useful shortcut
$url = $_SERVER["PHP_SELF"]."?";

// start point and ordering
$start = ( isset($_GET["start"]) ) ? $_GET["start"] : 0;
$sortby = ( isset($_GET["sortby"]) ) ? $_GET["sortby"] : $df_sortby;
$ascdsc = ( isset($_GET["ascdsc"]) ) ? $_GET["ascdsc"] : $df_ascdsc;

// allowed image types
$sfxs = array(".JPG",".jpeg",".png");

// get the current directory path:
$curdir = dirname(stripslashes($_SERVER["PATH_TRANSLATED"]));

// get folder delimiter for this system:
$slash = ( strstr($curdir,"\\") ) ? "\\" : "/";

$thumbdir = $thumbdir;



/* READ DIRECTORY */

// create array to hold filenames and information
// $images[n][0] = name
// $images[n][1] = date
// $images[n][2] = size
$images = array();

@ $handle = opendir($curdir);
if ( !$handle ) {
	error("could not open directory!");
	exit;
}

i can only assume its this line:
$curdir = dirname(stripslashes($_SERVER["PATH_TRANSLATED"]));

The php's fine - maybe you have to change the permissions on the directory?

[davieboy]

i have done, changed both the image file and the thumbs file.

tried both 755 and 777

if i chomod the images file to 777 i get 500 internal server error :bemused:

[davieboy]

ok my error log is giving me this

Premature end of script headers:

on the index page

[davieboy]

i changed this line
$curdir = dirname(stripslashes($_SERVER["PATH_TRANSLATED"]));
to
$curdir = dirname(FILE);

and it worked.

one other thing, it is very hard to veiw the thumbnails, (ie very faint)
is this a GD image issue?

[rikmoncur]

I remember changing some bits of the script:

imagecreatetruecolor() and imagecopyresampled()

but it didn't make a huge difference.
