If you have the rquirement to add a image in a session then add the image path in that session and retrieve where ever you want like this.

Session["UploadImage"]=imagepath;
Or
Session["ImageObj"]= ImageObj;

can we get image in session using java script ?

From javascript it is not possible. From .net we can store the image object in to a session.

It's not a good idea to store the whole image in a session variable. It will use a lot of memory unnecessary. You should save it to disk first and then store the saved image path in a session variable.

C#

var savedFilePath = @"c:\file.jpg";
fileUpload.PostedFile.SaveAs(savedFilePath);
Session["SavedFilePath"] = savedFilePath;

how can i upload image & store image path into session using java script ? have u any idea about it ?

StianSandberg 17-Jul-12 4:30am

you can't access session-variables directly from javascript. You have to post the form to your server (using a form), then you save the image and store the image path to a session variable just as shown in my example code.

hi hussain,

storing image in session is not a good idea to your application, it degrades the performance of ur application as it consists too large space. instead storing whole image in session u just store that image path in session.
it works fine and will improve ur website performance.
