Ive been working on automatically adding products to Magento from a 3rd party XML feed. Its fairly easy to do, however I couldint find much information on how to attach images to a product, and then how to set a product image as thumbnail, small image and base image.
The code to add an image to a product in Magento is:
$product->addImageToMediaGallery($imagePath, array('image','small_image','thumbnail'), false, true, $productData['data_display_name'] . " " . $productData['data_artist_display_name'] . " " . $productData['data_catalog_number']);
It is the array(‘image’,’small_image’,'thumbnail’) which tells Magento that you are wanting to use this image as the small image, thumbnail and base image.
