Hello Steven, many thanks for the speedy reply.

I have tried both suggestions and still no go.

Forgot to mention that on install of the plugin, it wouldn't activate because of permissions. After, setting al permissions correctly and still not able to activate,  searched the forum and followed your suggest and commented out a few lines of code that checks for 777 permissions. At that point it activated and was able to create a gallery based on the media library. However, ultimately would like to use the Picasa feature.

Thanks again, Y

Hi Steven,

Really appreciate your speedy responses and detailed investigation.

Unfortunately nothing suggested worked. I create a new post and gallery using picasateam & VegasWeekend and the same error showed. The page is http://villaravellogrecamore.it/tester

As you probably saw from the site, the current used is called Traveifly v1.4.31. It has a built-in slider for the front page. Is this an issue, conflict? Its seems to be well behaved so far. Also, I deactivated all Plugins except SV.

The error message mentions Gallery XML. Is that a file created from the Picasa feed. If so where is it stored on the host? How is the  Picasa feed handled? Does it store temporary data?

Many thanks a gain, Y

I don't think so. (It does not have any of the obvious signs that are usually associated with a conflict.)

The gallery XML file (the file containing the image data) is generated dynamically by WP-SimpleViewer's 'gallery.php' file.
The XML file for your 'tester' gallery can be examined by viewing it directly in a browser: http://villaravellogrecamore.it/wp-cont … llery_id=2
As you can see, there are no <image> entries in the file (which is the reason for the 'No Images Specified' message being displayed).

Try saving the following code into a file named 'picasa.php', upload it to your web server and open it in a browser.
The URLs of all the images and thumbnails in the Picasa Web Album should be listed as text.
(You can change the Picasa User Id and Picasa Album Name at the top of the file to select a different Picasa Web Album.)
The code uses the same routine that WP-SimpleViewer does but with all error trapping turned off.
What output do you see on-screen?
Also, what version of PHP do you have installed on your web server?

<?php
$picasa_user_id = '103574814608072251259';
$picasa_album_name = 'newgallery';
$picasa_feed = 'http://picasaweb.google.com/data/feed/api/user/' . $picasa_user_id . '/album/' . $picasa_album_name . '?kind=photo&imgmax=1600';
$attachments = simplexml_load_file($picasa_feed);
echo 'Picasa User Id: ' . $picasa_user_id . '<br />';
echo 'Picasa Album Name: ' . $picasa_album_name . '<br /><br />';
echo 'Total number of images: ' . count($attachments->entry) . '<br /><br />';
if ($attachments) {
    $counter = 1;
    foreach ($attachments->entry as $attachment) {
        $media = $attachment->children('http://search.yahoo.com/mrss/');
        $media_group = $media->group;
        echo 'Image #' . $counter . ': ' . $media_group->content->attributes()->{'url'} . '<br />';
        echo 'Thumbnail #' . $counter . ': ' . $media_group->thumbnail[1]->attributes()->{'url'} . '<br /><br />';;
        $counter++;
    }
    echo "Done.";
}
?>

Here's the output when I run the script on my own web server:

Picasa User Id: 103574814608072251259
Picasa Album Name: newgallery

Total number of images: 5

Done.

Running the script on its own takes both WordPress and WP-SimpleViewer out of the equation and the problem seems to lie somewhere between your own web server, your web server's PHP version/configuration and the script itself.

Try running phpinfo(). Save the following code into a file named 'phpinfo.php', upload it to your web server and open it in a browser.

<?php
phpinfo();
?>

Please let me know what version of PHP your web server is running and scroll down to (or search for) the SimpleXML section and check whether or not it is enabled. It sounds like it might be disabled and this would certainly account for the problem you are experiencing as the script to fetch the images from Picasa Web Albums relies on the PHP simplexml_load_file() method.
