Adding images to product gallery — Can't get media type to stick

[AF]

I'm trying to add base, small, and thumbnail images to all of my products programmatically. The images are importing fine and being placed into \[code\]/media/catalog/product\[/code\] as expected, but only 'Base Image' is selected when I view the product's images in the Magento backend.I'm looping through each product in the catalog and running:\[code\]$mediaArray = array('thumbnail', 'small_image', 'image'); $file = Mage::getBaseDir('media') . DS . 'import' . trim($imageName);try { $product->addImageToMediaGallery($file, $mediaArray, false, false); $product->save();} catch (Exception $e) { echo $e->getMessage();}\[/code\]All of my image names start with a slash, and the images themselves are uploaded to \[code\]/media/import\[/code\]. I'm attempting to mimic what the Mage product importer would do.Any insight on why the small and thumbnail flags aren't being set would be greatly appreciated!
