Just wrap this InputStream and scan for your boundary. It would certainly help if you had included the chunk length in your boundary string. But I don't see a problem here.

Re: Reading Chunked Stream using HttpClient
Odi, Yes, you are right. If we access the URL from broweser, it opens up a file dialog box and starts filling in bytes and there is no end to it unless we close the window. We are able to read the stream with get.getResponseBodyAsStream(). The stream is image bytes delimited by an ascii string "--myboundary", So I guess i just need figure out an easy way of cutting this stream into bytes for every occurence of that string. That sounds more of an IO issue. Any ideas? Thanks for your time and response.

You must therefore either parse the response stream by yourself or use an existing Multipart-MIME library to decode the multipart stream. You may want to have a look at the Commons FileUpload code which does exactly that or at Multipart-MIME Email handling code which must do a similar thing.
