Upload file extension being stripped from .jpeg files

[badarac]

Site is running 1.5.7b and some products have text/file attributes for customers to upload images. On the product page, the files is selected from the desktop and when the product is added to the cart it displays the full file name and extension. On checkout success, the order is written to the orders.products_attributes table, the products_options_values field is written as file-id. (313. instead of 313.jpeg for example) when the uploaded file extension is .jpeg. The file is uploaded in the images/upload folder with the correct name. If the file extension is .jpg it works as expected. I'm struggling to find the cause of this. Can anybody point me in the right direction?

Compare your copy of includes/classes/upload.php to a fresh download from 1.5.7b (your version).

They compared fine

I should also add that this code appears to relate to the actual upload and not writing the uploaded file name to the database. No errors are received that it is an invalid file type and the file is written with the correct extension.

OK, how about includes/classes/order.php - any changes?

The only change is to the section building the confirmation email at around line 1018

      $this->products_ordered_html .=
      '<tr>' . "\n" .
      //RB mod - Product Image            
      '<td class="product-details" align="left" valign="top" width="30">' . zen_get_products_image($this->products[$i]['id']) . '</td>' . "\n" .
      //RB mod - Product Image
