As far as errors go, this is about as descriptive as Google gets: you exceeded your quota.

Google’s quota limits are 10,000 API calls a day, and 75,000 base URL accesses (the base URL is the URL for an individual image).

Each time you display a gallery, you are making one API call. If your page has 5 galleries, it is making 5 API calls. If that page is visited by 200 people in a day, it will make 1000 API calls. Each time you reload the page you are making an additional API call.

Now, if each gallery has 100 images, you are making 100 base URL calls to display the images on your page. When you click on a photo to see it enlarged, it is making an additional base URL call. Using the same numbers as above, if each visitor of your site is going through each photo in each gallery, you are looking at 5 * 200 * (100 + 100) = 200,000 calls. That is significantly above the limit.

My guess is that you might have hit reload multiple times and gone through each gallery.

The best way to not step over your quota limits is to use your galleries judiciously. You can follow practices such as using the more button, or the show_gallery button, which will ensure that fewer images are shown on the main page, but more show up when you click on the button. That way a simple reload will not make API or base URL calls.
