We are building several sites for several clients which will be using images from the manufacturer.  Our dev team wants to insert the manufacturer's url for the images, instead of actually downloading the image and hosting on our server.  There are thousands of images, so downloading images to our server will be time consuming, so we are looking for a shortcut.... however I'm concerned this will cause other issues. Is using manufactueresdomain.com/12345.jpg going to cause SEO issues?  will this generate Google penalties?  Since we are not able to control the image file name, we cannot optimize it.  We will add Alt text and Title tag for each image, but the file name is random characters.  How important is the file name for SEO?

I have an issue with a few page titles not matching the title I have In WordPress.  I have 2 pages, blog & creative gallery, that show the homepage title, which is causing duplicate title errors.  This has been going on for 5 weeks, so its not an a crawl issue.  Any ideas what could cause this? To clarify, I have the page title set in WP, and I checked "Disable PSP title format on this page/post:"...but this page is still showing the homepage title.  Is there an additional title setting for a page in WP?
