[Plugin: AutoThumb] SOLUTION: Make AutoThumb work on WP Multisite

Here’s a quick & easy solution for making this great plugin work on a WordPress multisite installation.

PLEASE NOTE: The following will require you to make minor code adjustments to 2 files. If you later update the AutoThumb plugin, OR update your permalinks, the changes will be overwritten and you will need to re-add the necessary code to those 2 files.

[Step 1]

Locate /wp-content/plugins/autothumb/image.php and add the following code right before the line which reads include('phpthumb/phpThumb.php'); :

/* Multisite Compatability Hack */
include '../../../wp-config.php';
include '../../../wp-load.php';
if( MULTISITE == true && preg_match('%'.$base.'.*/files/(.+)%i', $_GET['src'], $matches) ){
	$_GET['src'] = BLOGUPLOADDIR.$matches[1];
}

[Step 2]

Locate the .htaccess file in the root of your WordPress installation, and add the following code directly after the line which reads RewriteRule ^index\.php$ - [L] :

RewriteRule ^YourSiteName/images/(.*)$ /YourSiteName/wp-content/plugins/autothumb/image.php?$1 [QSA,L]

Make sure to replace the word YourSiteName with the name of your actual site. For example, if your site is at https://www.someblog.com/MyKittyBlog/ , you would change the above to read as follows:

RewriteRule ^MyKittyBlog/images/(.*)$ /MyKittyBlog/wp-content/plugins/autothumb/image.php?$1 [QSA,L]

Note that, with this code, you will need to add a RewriteRule line to your .htaccess file for each one of the sites where you want AutoThumb to be able to function. There is probably a better way to do this, but I unfortunately am not a Regular Expressions genius.

Questions, comments, or suggestions for a better way to do this? Post them here.

Hopefully the plugin author will update AutoThumb to include multisite comparability in the future. ??
