For info I had problems using HTMLRenderer on Azure Websites for rendering HTML to image. MS has some known issues with GDI and Azure Websites and their fixes are a work in progress.

Rendering on a Free Azure Website resulted in an Out Of Memory Exception because handles are not available. Rendering on a Basic Azure Website resulted in black or empty images being saved to stream.
However, if you use RenderToImageGdiPlus it works both on Free and Basic/Standard as far as I can see.
