Automatically use remote or local images in Zen-Cart. Contribution:Web images – Zen Cart(tm) Wiki

For my showcase application I wanted to show images directly linked from an external site and not only store them on the local server; nevertheless both methods are working.

I changed the database field length to accept longer names and I may now enter a Products_image like http://www.siteurl.com/images/externalimage.jpg.

I have changed some code and the result may be seen at rcmarket.net.

Changes:

includesfunctionshtml_output.php line 165:

//by rl if image is located on the web, strip any local path  
    if (strstr($src, 'http') != '0') {
	  $src = strstr($src, 'http://');
	}

    // use old method on template images  by rl: test for http
    if (strstr($src, 'includes/templates') or strstr($src, 'includes/languages') or PROPORTIONAL_IMAGES_STATUS == '0'  or strstr($src, 'http') != '0' ) {
      return zen_image_OLD($src, $alt, $width, $height, $parameters);
    }

Basically you assign the constant DIR_WS_IMAGES to a variable $imagepath. 

Then add the short method to check if the image starts with http.
If it does up then set imagepath to blank. else use DIR_WS_IMAGES.
You must also insert $imagepath in place of DIR_WS_IMAGES in the zen_image function calls.

In addition to these files a number of other files need 
to be updated. All products, featured, new, cart, listing, product info and maybe others. 
Make sure to pay attention to the file product being referenced
for example:
$featured_product->fields['products_image']
$new_product->fields['products_image']
$listing->fields['products_image']

etc.

The shopping cart also must be updated.
