Look into using DIME and WS-Attachments. I have an article on this very
topic here:

An Extensive Examination of Web Services: Part 10
http://aspnet.4guysfromrolla.com/articles/090804-1.aspx

In fact, you may want to read the entire (currently) 10-part series on
Web services I've written... it starts here:
http://aspnet.4guysfromrolla.com/articles/100803-1.aspx

You could also pick up a copy of my .NET Web Services DVD at
http://www.amazon.com/exec/obidos/ASIN/B0002AHVPA/4guysfromrollaco -
it's a two-disc DVD with ~10 hours of training on creating and consuming
Web services, examining the core Web service standards along with WSE.
In fact, the *entire* ~30-minute Chapter 14 on using DIME and
WS-Attachments can be found online at
http://dvpress.com/ecom/Downloads/Sample_Clips.aspx

Happy Programming!

well yes u can upload the image file by calling web service method,
the Web services toolkits support adding attachments to SOAP messages using
an object model, so that you are abstracted from the details of populating
HTTP headers and building the compound SOAP message. Thanks to the generation
of Web service proxies, in a few lines of code you can create a DIME
attachment from a binary stream, attach it to the outgoing attachments
collection, and invoke the Web service method, as shown here for a .NET Web
service.
DimeAttachment attachment =
new DimeAttachment("image/jpeg",
TypeFormatEnum.MediaType,
data);
svc.RequestSoapContext.Attachments.Add(attachment);
svc.SignAttachment(text);

more information about Soap specificaion for attachment can be found at
