attributes - Magento: Difference between loading product through collection than product model -

-

so trying load product through collection criteria, didn't have sku or id when did following

 $prodmodel->getcollection()         ->addattributetofilter('visibility', $visibility)         ->addattributetoselect('*')         ->addcategoryfilter($cat)         ->addattributetofilter('attribute_1', $sattribute_1)         ->addattributetofilter('attribute_2', $attribute_2)         ->addattributetofilter('type_id', 'configurable')         ->load()         ->getfirstitem()

when doing got product wanted reason didn't have of attributes, though specified "*" attributes. 1 not getting media gallery attribute. ended doing saying getfirstitem()->getid() loaded product , worked find.

i don't understand whey loading product catalog product model have more attributes.

i understand asked how of attributes notice mention media gallery attribute specifically. there happens shortcut getting product image's final url.

(string)mage::helper('catalog/image')->init($product, 'media_gallery');

casting string calls __tostring performs cleverness. can apply resizing, rotation, watermarks, etc. after initialising.
