We are getting timeout exception when retrieve the uploaded image url as: http://i3.ebayimg.com/07/i/000/d6/78/ceb5_1.JPG?set_id=7. however; every thing works fine if the "?set_id ..." is removed from the image url .
What is the problem? What "set_id=7" is for?
Summary
The possible cause for the timeout is that some third party security products will mangle or block GETs of parameterized JPG URLs. As a result, for clients that access or retrieve images should not include the "?set_id=7" after the ".JPG".
The set_id info returned in the upload requests to the POST and XML interfaces is there so the client creating the picture can store along with the base URL extra information that identifies what sizes are available (in the normal case where multiple sizes are created per upload).
