Magento – Resizing any image in Magento

imagemagento-1.7

Magento has this great helper to resize product images but I'd like to resize any image from PHTML template files.

Now I could use the Varien_Image (lib/Varien/Image) class but it doesn't implement caching which is in my opinion required for resizing.

Is there an extension you can recommend for this or any other solution or should I build my own?

I wasn't able to find a solution in the form of an extension so build my own which you can download on github.

@Philwinkle's suggestion to use Googles Mod Pagespeed would have been easier but unfortunately in the case it was not possible to modify the server configuration.

Usage

<img src="<?php echo $this->helper('rkimages/image')->run('path/to/your/image')->resize(135); ?>" alt="Your Alt Here" />

The number within the URL doesn't represent the scale or pixel dimensions of the image - it is the store view.

All directories/files are automatically created the moment the front-end is viewed and the resize code is executed. It is that simple.

So as you have discovered the helper init function actually just populates lots of attributes and then returns itself.

If you look at file /app/design/frontend/base/default/template/catalog/product/view/media.phtml line 40 you will see the following:

$_img = '<img src="'.$this->helper('catalog/image')->init($_product, 'image')->resize(265).'" alt="'.$this->htmlEscape($this->getImageLabel()).'" title="'.$this->htmlEscape($this->getImageLabel()).'" />';

I would assume that looking at this it is safe to cast the helper as a string and use the return string as the image path. The helper has a __toString function that will be used when you perform the cast to string.

Edit

When assigning the imageUrl variable to the array it will only assign a reference so you will always get the last one when you come back to this array in the template. If you really want to have the object in the images then try the following.

$image['imageUrl'] = clone $imageUrl;

This will create a separate copy of the object each time. Personally I think that casting it would be the best solution though.
