I think the comments and ratings make the big difference for the stethoscope if the second picture have his thumbnail generated. Because I have some who don't... but it's probably the ratings.

For the Lebanese dish, the keyword "sfiha" is maybe a misspelled term for the search engine. Because StockXpert does not have any speller checker who give the information if this keyword is supported by the search engine, like other sites have. But I don't know how the search engine is working exactly. If it's like IS, it's return you to an other keyword if it's not supported..                                                                 

It can be a search engine problem too. But for the stethoscope it's sure is the ratings. I have similar files uploaded at the same time and the rated one have a lot more views then the one whit no rating.
