fatal error with imgbrowz0r

[sharpie]

Hi

Other than some HTML and CSS scripts I’ve not done a great deal with websites – having watched the tutorial on imgbrowz0r I thought it would the answer to a gallery I’d like to include on my new photo site.

So I duly downloaded and followed the tutorial several times and viewed similar code on another site and off I went…

Sadly though I’m slowly picking up limited PHP knowledge a fatal error in he index.php has me flumaxed, I know it’ll turn out to be something really basic but the error reads Fatal error: Call to undefined method imgbrowz0r::init() in F:xampphtdocsMySiteindex.php on line 137 the code reads $galleries->init();

Can anyone put me out of my misery and point me in the right direction.

Cheers

Jon

Update – this is the code for index.php which is giving me the fatal error, it’s as copied from the screen cast

Code:

dirname(__FILE__).’/gallery’,
‘cache_dir’ => dirname(__FILE__).’/cache’,

‘main_url’ => ‘http://localhost/test/index.php?q=%path”‘,
‘images_url’ => ‘http://localhost/test/gallery’,
‘cache_url’ => ‘http://localhost/test/cache’,

‘dir_thumbs’ => true,
‘random_thumbs’ => true,
‘read_thumb_limit’ => 0,
);

$gallery = new imgbrowz0r($config);

?>

My photo Gallery

init();

$gallery_breadcrumbs = $gallery->breadcrumbs();
$gallery_pagination = $gallery->pagination();
$gallery_statistics = $gallery->statistics();

//displanavigationy
echo ‘

‘, “nt”, $gallery_breadcrumbs, “nt”, $gallery_pagination, “nt”, $gallery_statistics, “n”, ‘

‘, “nn”;

echo $gallery->browse();

echo “

“;

?>

this is the code from the imgbrowz0r.php – more or less out of the box from download.

i’m using a a folder nameed test obviously and as per the screencast 64 have set up folders, cache, css, images, gallery, inc, js, the imgbrowz0r php file is located in "inc" and I have loaded 4 random images of my desk top into the "gallery".

The fatal error is in line $gallery->init();

which I understand loads an object? The only thing I can summise is the the imgbrowz0r php code is different in Chris version to that I’ve downloaded – I can’t for example see any random function in this version!

Thanks for looking.
