VT-resize (great alternative to timthumb) : Errors cropping (litespeed, centos 6.3)

Question

I'm using from several months wt-resize, a script to resize images on the fly. It works very well until now...

I've changed hosting provider. I'm using now Centos 6.3 (no control panel) + Litespeed (php 5.4.11) and i have following errors:

Warning: getimagesize() expects parameter 1 to be string, object given in     /home/*****/***/
 Warning: basename() expects parameter 1 to be string, object given in /home/

According source page where i see this error it seems that this script isn't able anymore to return the name of the file.

Do you have any workaround ?

I'm asking about this script because Wordpress doesn't resize images on the fly. If you add to functions.php a new size, for example

add_image_size( 'archivio', 250, 140, true ); 

you resize every single image you upload online to the size 250x140 and i'm interested only to resize what i want

Here's the error i have on the source page where i'm using this script

 <b>Warning</b>:  getimagesize() expects parameter 1 to be string, object given in       <b>/home/***/public_html/wp-content/themes/***-v16/functions.php</b> on line <b>139</b><br   />
 <br />
 <b>Warning</b>:  basename() expects parameter 1 to be string, object given in
 <b>/home/***/public_html/wp-content/themes/***-v16/functions.php</b> on line <b>140</b>
 <br />
 <img src="http://www.***.com/images/2013/02/" width="" height="" />
</a>

More details:

Previous server configuration was Centos 6.3 + Nginx + PHP 5.3.2.1. I can confirm this script was working well :(

The Problem here lies within the Plugin, which utilizes the deprecated Function image_resize. I'm not 100% sure that this is the only Problem, but try rewriting the Plugin using the new [WP_Image_Editor][1] Class.

The next Step to check is if the Plugin can write the files, and if the directory permissions are set correctly.

See Line 128 of your code:

$new_img_path = image_resize( $file_path, $width, $height, $crop );         

This line returns a String if executed correctly, or an WP_Error Object on Failure. I'm pretty sure this is where your Plugin goes wrong.

If you do not want to rewrite it (which I highly recommend), try writing a small Plugin to find out if your image_size works as expected, or if you have to change your Server's settings.

For the Image functions to work, you have to have your Uploads Directory writeable for your Plugin Files.
