A note for anyone wanting to use images FO.NET with Azure:
Local Storage uses brackets in the directory name which results in images not being found. I have tracked it down the this piece of code:
if (href.StartsWith("url(") && (href.IndexOf(')') != -1))
href = href.Substring(4, href.IndexOf()') - 4).Trim();
in Fonet.Image.UriSpecificationParser.ParseUri. This chops off the end of the path name after the bracket, and consequently the image isn't found.
