[Code]....
want a file upload control for uploading image in which when user select the image ,
i want to show it in image control after he finished browsing the image.
I have a fileupload control in a contentplaceholder in a masterpage. I have to preview the image whenever I browse an image beside it in an imagecontrol.
My application is running on a different server .So I can't give the filepath of my local system.
Also I don't want to store the image in any location and i'm not supposed to use any session variable to pass it to generic handler.

I'm having an image in my page displayed to clients form a folder under same apllication folder,I also have a form in the same page that accepts an image file to be uploaded. The image that is uploaded via this form should take the place of the image that's displayed in the page with the name newly givven at runtime. The new image should be uploaded in the same directory with the new name provided, which means it overwrites the previous image.

in C# code I wrote these:
[Code]....
But it does not work. Image is like Previous. Note that ImageOperations.ResizeFromStream() method resizes and saves the image to a specefic folder. actually I should trigger a Postback to Update the Update Panel but How to do that. I usedUpdatePanelNew.Update(); but it does not work!
I'm using a slightly modified version of Valum's upload [github link], I've modified it to upload to a database but haven't modified the javascript that it is using to get the file into the Request as an InputStream. The following line of code is failing in IE 8 but is confirmed to work in Chrome. using (Image imgInput = Image.FromStream(Request.InputStream)) The error received is "Parameter not valid". It appears to be having an issue with the Input Stream being used but it exists/has data (not sure how to validate if the data is good or not).

i am working on an ecommerce application, user will be uploading several images of a product, instead of stripping the size (i.e the KB or MB size) after uploading it on the server, i want to strip the size of image before uploading it to the server ( bringing the size from any thing over 30KB down to 30KB) i.e on the client machine itself and then upload it to the server. i understand that this requires a download on the client machine which makes me ask the following questions :
a. can i use a java control in dotnet since java control can be used on all OSes
b. is there any dotnet control that might be userfriendly to all OSes
