The latest released version is available for download from the Zen Cart site, via this link. If you need basic installation help, and neither this information nor the included readme does not help you, please visit the Image Handler v5.x Support Thread.
This version of Image Handler requires Zen Cart v1.5.7 or later and has been tested with Zen Cart v1.5.8 and v2.0.x on PHP versions up to and including PHP 8.3.
Image Handler 5 simplifies the management of product images (particularly the management of additional product images), and to help improve page performance by optimizing those images. Product images (based on your image settings) are created in the Image Handler5 bmz_cache directory. The original images are not modified, so it's perfectly safe to use on an existing store.
Image Handler 5 enables you to use GD libraries or ImageMagick (if installed on your server) to generate and resize small, medium and large images on the fly as they're required. You can simply upload just one image or you can have different sources for medium and large images. Image Handler 5 further enables you to watermark your images (overlay a second specific translucent image) .
This contribution includes a powerful admin interface to browse your products just like you would with the Attribute Manager and upload, delete or add additional images without having to do this manually via FTP. IH5 works fine with mass update utilities like EZ-Populate and Database I/O Manager.
IH5 works with default Zen Cart functionality, it does not replace it. There are a couple of threads which explain what Image Handler is and more importantly what it is not. It is suggested that you read everything before you install IH5. Here are some additional FAQs which discuss how product images and the override system work in Zen Cart. If you are new to Zen Cart and web development, you should read these threads before you install Image Handler5.
