Product Images Help

I recently added product images through my database to match the imported data of my store. Unfortunately the images arent showing up in the store. I've followed other suggestions and cleaned out the image cache but that hasnt worked. I also resized the images under settings but no luck. The product images are on the server and the image reference is correct. Anyone have an idea how to sync the database to get the images to show in the admin and store? Thank you.

Please post a link to the website to verify the images. If you try and access the original image url(not the cache on) in the browser directly, does it work.
