Hello,
I have successfully implemented the functionality of displaying image preview of the image being uploaded before actually saving the image by reading the article Show image preview before actually uploading the image in asp.net
Its works like charm. But when post back occurs on the page then the preview disappears. Is there any solution to maintain the image preview even after postback?

May be, instead of complete page post back, doing partial postback through ajax update panel can help .
