* there is no (built-in) way deleting images from the cache.
* images with the right width are also cached. why?
* only works when there is exactly one space and no other tags between ‘<img' and 'src=":..:"'. This makes is not working with JCE image-manager and others

If will improve the code and send if to the author.

reg, m

I do some tweak including
– apply patch from bug tracker
– apply with image inside “images/stories/” only
– with a longer width image only

code (only php file ) is available at

I use php5 on ovh server please give me a solution

Since the public servers (even the paid ones) NEVER have imagemagic it’s completely useless to write code which relies on it. Here is a modified version (open up imageresize.php and replace the getCache function) which doesn’t require imagemagic. It works perfectly, enjoy:
function getCache($imagePath, $restofTag)
{

//first, check to see if the rest of the tag has the width parameter
$wPattern = ‘/width=”([^"]*)”/’;
preg_match($wPattern, $restofTag, $match);

if($match[1] > 0) {
$imgData = getimagesize($imagePath);
$width = $match[1];
$height = round(($width/$imgData[0])*$imgData[1]);
} else{
$imgData = getimagesize($imagePath);
$width = $imgData[0];
$height = round(($width/$imgData[0])*$imgData[1]);
}

$fileName = getFileName($imagePath);
if($imgData['mime'] == “image/png” || $imgData['mime'] == “image/x-png”){
$source = imagecreatefrompng($imagePath);
} elseif($imgData['mime'] == “image/gif”){
$source = imagecreatefromgif($imagePath);
} else{
$source = imagecreatefromjpeg($imagePath);
}
$imageDir = getDir($imagePath);
$imageCacheDir = “cache/” . getDir($imagePath);

$fileNameCache = $width . “-” . $fileName;

$cache = $imageCacheDir . “/” . $fileNameCache;

// create the cache if it doesn’t exist
if(!is_dir($imageCacheDir))
mkdir($imageCacheDir,0777,true);

// create the file if it doesn’t exist
if(!file_exists($cache)) {
$new_image = imagecreatetruecolor($width,$height);
imagecopyresampled($new_image,$source,0,0,0,0,$width,$height,$imgData[0],$imgData[1]);
imagejpeg($new_image,$cache);
chmod($cache, 0777);
//exec(‘convert -resize “‘ . $width . ‘” “‘ . $imageDir . “/” . $fileName . ‘” “‘ . $cache . ‘”‘);
}

if(!file_exists($cache))
return null;

return “”;
}

‘Warning: mkdir() expects at most 2 parameters, 3 given in [path omitted -J]/plugins/content/imageresize.php on line x’ problem. Did anybody find a cure for it in the end? can it be sorted?

Hi, just thought I would share this.
Recently I tried to backup/migrate a site from a webhost to my computer running XAMPP. I backed up with JoomlaPack and used kickstart.php to install the site on my XAMPP in windows.
The Joomla site does not run a lot of extensions, however I have installed Image Resize. http://extensions.joomla.org/extensions/5694/details a great plugin.
When I installed the site on my local machine, no images would display in the front-end, but they did display in the backend. I tried several options; backing up the site using FTP and PhpMyadmin – i.e. not using JoomlaPack, disabling .htaccess, purging the cache, saving articles. Nothing worked. When I tried migrating to a sub-domain on my webhost, the images would display in the frontend without any problems.

Solution: After running kickstart.php, enter the backed and un-publish the Image Resize Plugin, purge the cache and expired cache and publish the Image Resize Plugin again. Presto!.

Is it weird that this problem would occur on migrating to XAMPP but not to a linux-based webhost. Oh, well I found a solution.

A big thank you to the developers of Joomla, JoomlaPack and Image Resize.
