Thanks. Sorry if there are multiple messages coming through for me, my Provider had blocked this e-mail address (twsocket....) thinking it was spam.

The browser demo is slightly convoluted due to handling URL protocols such as res and file, as well as http, and due to caching of images. Essentially, there is a dynamic array FImageHTTPs of TImageHTTP components, four at the moment, this component is defined in urlconics.pas and includes HTTP : TSslHttpCli which does the hard work. When the browser component needs to display an image in GetImageRequest, the URL is added to a queue Pending and a windows message WM_Next_Image sent, which eventually causes WMNextImage to be called. This checks if one of the FImageHTTPs instances is free and if so starts a download. When the download completes, ImageRequestDone is called which processes the download and calls HttpSessionFree. This clears the last session and checks Pending for any more URLs and sends another windows message to trigger the next download. So Pending is the real queue.
