Hi guys,

I kindly ask you to implement the following piece of code in the next release of MobileJoomla.

Before lines 181-182 in imagerescaler.class.php:

if(file_exists($dest_imagepath))
return $dest_imageuri;

Please add the following:

if(substr($dest_imageuri,0,2) == '//')
$dest_imageuri = substr($dest_imageuri,1);

The sense behind this check is that on an IIS webserver, if an image source starts with 2 double slashes (e.g. "//images/stories/Resized/image.gif" instead of "/images/stories/Resized/image.gif"), the rescaled image is not displayed. The above code takes care of this issue and reforms the URL if necessary.

Cheers,
Eric

Hello,

is it possible to make this instruction compatible with PHP5.1 :

$src_imagename = pathinfo($imageurl, PATHINFO_FILENAME);

I needed to create a function to verifiy if the constant "PATHINFO_FILENAME" is defined, because my provider only has PHP5.1, and this was implemented in 5.2

  function pathinfo_filename($file)  {
    if (defined('PATHINFO_FILENAME')) return pathinfo($file,PATHINFO_FILENAME);
    if (strstr($file, '.')) return substr($file,0,strrpos($file,'.'));
  }

$src_imagename = ImageRescaler::pathinfo_filename($imageurl);

thanks,
Jerm's
