Need to display image in ASPX page that has long url

问题

Scenario: Within ASP.NET site, I have an ASPX page where within OnLoad event, I set the imageUrl for one of the image controls. This URL value comes from an external source and the image is not getting displayed and I found out it is because the URL is too long.

How to display images of longer URLs? Should I use POST with javascript or any other options to achieve? The values within the URL are crucial and I can't loose some of the parameters.

Please suggest.

Code in OnLoad event is something below.

        Image pImage = new Image();

        pImage.ImageUrl = imageFile; // imageFile is the one having long URL.

Update 1: If I am able to achieve the POST in OnLoad, then I think image will get displayed. Please suggest how to acheve this in OnLoad.

Update 2 : The actual URL is below.

Update 3: I now get HTTP 403 forbidden error when I try to browse the URL in a separate window. Any suggestions?
