Unfortunately there's no good way to do this as Web Connection is limited by FoxPro's 16 megabyte string limit and the request data is loaded into memory.
What you can do is use an upload component (I just posted an ASP.NET based example using plUpload) to push files to the server and then use some client side code to notify the Web Connection application that a file is ready. So in the image upload example you could have the client make an AJAX call to your FoxPro app to do something once the file is ready. It's hacky but it would work...
