Image Problems – WordPress Site Migration

Hey everyone

I recently developed a site locally on a MAMP server i setup on my mac

I have just migrated the site using backup buddy to my webserver

Everything seems to be working except some of the images are not showing up?

These are just the images that are being used in custom post types such as the homepage nivo slider and also image previews on the gallery page

Images on pages all work fine.

This is weird as these images are all located in the same uploads folder?

Any ideas anyone?

Thanks

Ollie
