Greg... I took a look at your Gallery... for example, your "Alice's Restaurant" trip pics...they are all 500k, 600k...800k each.
They only need to be
one-tenth that size...the large-format, high-res pictures are wasted for display on the web.
That is what's using up all your quota.
Try a photo-resizer or editor to bring those pics down to 800x600 jpegs.
