Image upload problems

Hello. Are there any known problems uploading images to albums? Perhaps issues with how the site plays with Mac browsers? I've tried multiple times without success, using both Safari and Firefox. Safari yields the error "Safari can’t open the page “http://priuschat.com/index.php?â€. The error was: 'lost network connection' (NSURLErrorDomain:-1005)" wheras Firefox (eventually) just yields a blank page. No image is transferred in either case.

Image uploads of this sort have worked for me on other sites.
