I have a fileupload control in my form which stores image to the SQL database as binary data.
BUT it stores as 0X000000.... I just realized that.
BUT IT DOESN'T MAKE ANY SENSE BECAUSE WHEN I PRINT THIS BYTE ARRAY IT SHOWS THE CONTENT.
This part is the server side code:
[Code]....
StoreToDatabase function:
[Code]....
DisplayFileContent function:
[Code]....
Displaying function shows like 2552162552240167470737001110960960025521906708667658777998101220131211111225181............BUT IN DATABASE it stores like 0X00000000000000000...

It seems that when trying to upload(save) an image taken by a mobile device to file, the orientation gets messed up and you end up with images that are rotated 90 degrees to either side. This is an issue I am currently having.
Code:
[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult AvatarEdit(HttpPostedFileBase NewAvatar)
{
//SAVE TO SERVER
string newid = Guid.NewGuid().ToString();
[Code] ....
Would I need to convert originalImage to a file type of HttpPostedFileBase or is there a more elegant way to save the file? I tried reconverting it to a stream and then saving it to file, but I failed miserably.
We have a scenario where we would like to allow our users to upload images to the site. We are running on ASP.Net. A quick search did not result in anything good. It would be great if the control is free/open source but we do not mind paying a little bit.

I have uploaded a .jpg image and resized as Small and Large thumbnail. The small image is (135 X 173) but after resizing the small thumbnail image file size is of 40.8 KB. And mostly all images (around 64) thumbnails having file size more than 40 KB. Due to which thumbnails taking lot of time to get display.
Is there a way through which we can reduce the image file size upto 8 to 12 kb, but without effecting image quaity??
Below is the source code that i am using for resizing an image:
If FileUpload1.HasFile Then
Dim stream As Stream = FileUpload1.PostedFile.InputStream
Dim x As String = IO.Path.GetExtension(FileUpload1.FileName).ToLower
If x = ".jpg" Or x = ".jpeg" Then
Dim image As New Bitmap(stream)
