yes work correctly thanks
but  some imges gets me error

Attempted to divide by zero.

Line 96: int sngRatio = origWidth / origHeight;
 Line 97: int newWidth = 160;
Line 98: int newHeight = newWidth / sngRatio;


whats the soulation for this error

be sure that before i post any thing i try more and raed about it to find answer ny self

then remove your the below method outside the fileupload.content.length condition

i belive that each user who uplaod profile user  will be username.jpg and i works fine and  i resize it to avoid lagre photos  to upload  the only error that when i save without upload it have to complete  the code and reszie the image and so it gets error in case no photo uplaod else i works fine and no error at all

I believe the below line is unique for each user


I believe, here user  is the user id and user will always upload .jpg file. 

therefor it is not required to save any details related to photo to database.

thankx frist i upload my photo to folder on my web application and only save path in database where it accept null value . i use
 if (FUpload.HasFile)
        {
// do something

{
   // do something
}

i ask if i can do something like this

 if (FUpload.HasFile=true || FUpload.HasFile=false )
{
   // my code to save data with or without photo path will run here
}

Hi,
        If your upload photo is not mandatory while registering the User details, then while saving the data just check like this


Note: I believe UploadPhoto filed in database is nullable
