Access the 'Developer Toolkit' from the Zen Cart administrator screen. In the search box, type 'DIR_WS_IMAGES.' This brings up all the pages that contain code to be modified. In each page, replace 'DIR_WS_IMAGES' with 'DIR_EXT_HTTP.' This tells Zen Cart to look for images externally rather than in the 'image' folder. This step is necessary only once.
Navigate to the Web server that contains the image that you are linking. If the images are stored on your hard drive, you need to upload them first. Sites such as imageshack.us and photobucket.com (and others) offer both free and paid services for image hosting. Alternatively, you could choose to host them on a private server, if available.
Right-click on the image once it is displayed in your browser and select 'Properties.' This brings up a window that displays the image attributes and location. Highlight the URL that appears next to the 'Path' field then right-click the selection and choose 'Copy' from the menu. Example text (without quotes): 'http://example.com/image.jpg."
Paste the URL copied in Step 3 into the 'Product Image' text box on the 'Product Attribute' page, and save the changes. Your external image should now be displayed correctly.
