i have a security image for user registeration,and i use Ajax to change picture when user can't read image,but there is
a problem:when user click "Change Picture" image change only for one time!(Image Create in Physically path,but Previous image Show in image Control)
i think,image control can't reload or physically path isn't refreshed!

Has the new image got the same name?

 If so try using a new name and deleting the old file.

I think the image is being cached. Add the below code to disable caching

Response.Cache.SetCacheability(HttpCacheability.NoCache)

Hi Ir.WebDeveloper,

You can use the javascript to change the image's url property, it will change the image.

<img id="banner1"/>

   var image;

    function loadbanners(num)
    {
       if (banners==1)
          {
             image="http://t3.baidu.com/it/u=1327186658,2151000171&fm=0&gp=12.jpg";
          }
       if (banners==2)
          {
             image="http://t3.baidu.com/it/u=3941030140,4260276935&fm=0&gp=20.jpg";
          }
       if (banners==3)
          {
             image="http://t4.baidu.com/it/u=3162174103,1403993499&fm=0&gp=-34.jpg";
          }

        var tt=document.getElementById("banner1");
        tt.src =image;
      }

Image Control Problem Mobile Web Forms
Converting some code from ASP.NET to ASP.NET Mobile Web. I find the Image Control is not working the same in the Mobile Web forms. I have a PDA application where the user inputs an airport identifier, then returns a .gif image to the PDA of the local NEXRAD radar for that area. Using mobile web forms the first image returned for a session continues to be returned, even though the image on the server has been updated with a new request. So I know a round trip is being made to the server. But locally the PDA picks up the first image generated for the session. I can work around this pr...

VB.NET web form Image control SizeMode
The "PictureBox" control in VB.NET has a property called "SizeMode". This allows you to choose how the image will display in the picture box if it is not the same size as the picturebox. However the "image" control for a VB.NET web form (in an ASP.NET application) does not have such a property, instead all images seem to be set to "StretchImage". I want them to be set to "normal", how can I do this? I thought of building my own user control but this would be silly because there must be a simpler way....

Displaying image from database(image datatype) to image control
