define('TEXT_PRODUCT_FREE_SHIPPING_ICON', zen_image(DIR_WS_TEMPLATE_IMAGES . 'always-free-shipping.gif', 'Always Free Shipping'));
Below is simplified from both of the discussions above and only with the basic.
<div id="logo1"><?php echo zen_image(DIR_WS_TEMPLATE_IMAGES . 'test.gif') . '</div>'; ?>
And from page source of my test it show as.
<div id="logo1">
<img width="240" height="160" alt="" src="includes/templates/future_zen_4/images/test.gif"/>
</div>
The image can be seen and under the override directory.
By viewing page source, always helps to trace, isolate problems, debug and minimize the time in development.
Note:
- the raw image size for the test.gif in above test is 240 x 160 px and no parameter was entered in the above test.
- the **alt="" ** is for the no alter text entered.
