Uploading Photos

I’m using Word Press to run our business website (www.theperfectpause.com) and am having trouble loading pictures in the, “e-Commerce/products” section of the admin-panel. I attempt to upload the individual pictures of our product in the “product image” and the uploading appears to take place but the sometimes it doesn’t work and leaves me with a gray box with “no product image” where the picture should be.

I’ve tried loading the pictures from a different computer and that isn’t solving the problem.

If anyone could offer a solution we would greatly appreciate it (and there might be some free tea in it for you).

Thank you!
