In the configuration under "Album list view" there is the option "Number of columns for the album list" which is defaulted as 2. When I try to change this it does not save the update. Is this what I need to change for a 4 column display or is what I am looking for not in the config?
That's not surprising, as that particular theme overrides the config setting by hardcoding the corresponding setting into the code. To undo that, edit themes/avalon/theme.php, find
$CONFIG['album_list_cols'] = 2; // sets "Number of columns for the album list = 2"
and comment out by putting two slashes in front of that line, so that it looks like this:
// $CONFIG['album_list_cols'] = 2; // sets "Number of columns for the album list = 2"
Alternatively, hard-code the number of columns to 4 like this:
$CONFIG['album_list_cols'] = 4;
However, you might run into issues with such a narrow fixed-width theme and four columns instead of just two of them: I'm sure that the author of the theme port has overridden that value on purpose. This depends to a great extent to the width you assign for album thumbnails; make sure that this is set to a small value.
The missing file information block is actuall a feature: the theme author appears to deliberately have changed that feature, because he changed
$picinfo = isset($_COOKIE['picinfo']) ? $_COOKIE['picinfo'] : ($CONFIG['display_pic_info'] ? 'block' : 'none');
echo "<div id=\"picinfo\" style=\"display: $picinfo;\">\n";
starttable();
echo $pic_info;
endtable();
echo "</div>\n";
to
$picinfo = isset($HTTP_COOKIE_VARS['picinfo']) ? $HTTP_COOKIE_VARS['picinfo'] : ($CONFIG['display_pic_info'] ? 'block' : 'none');
starttable();
echo $pic_info;
endtable();
, so he removed the wrapper that creates the toggle. Put that line back if you want to file info section to be toggled. Alternatively, remove the nav bar and get rid of the file info button that does nothing, making the file info section expanded permanently.
There have been some mistakes inside the file theme.php (that may reside in the original avalon theme as well; I haven't checked so far), which I edited out in the attached copy; just download the attachment and then rename your local copy back from theme.php.txt to theme.php. Finally, overwrite your copy of theme.php with the one I attached (keep a backup of your version just to make sure that I haven't introduced new issues). In the theme file I attached I have restored the file information toggle as it used to be.
