Solution 1

"Parameter Not Valid" is a generic error message from the GDI, which basically means "that isn't an image I recognise"

The most obvious reason is that whatever file you are trying to upload is not a valid image file, or is corrupt or incomplete.
Try saving the stream data in a temporary file, and examine it manually to see what kind of data the stream contains.

I stored list of object in session from a action method and retrieve from different action method. Using quick watch i can view all file information even file.InputStream.length, position, file name etc.

I've uploaded several image to flickr by checking image size, those are not uploaded(for network connection problem, willingly created.)are shown in the form of list in different view with Retry button and before call view list of objece(those are not uploaded in flickr)is stored in session. And when i click on that button sometime first image file of session variable uploaded in flickr properly, most of the time it throw that exception. Now if you give me a reference/code that will be more appreciated.
Thanks a lot

Thanks @OriginalGriff
I've tried the way you shown. I found what the problem is, "ObjectDisposedException was Caught"
I think this means file is closed.
Now how it can be reopen???

Please give me your valuable suggestion.

Thanksssssssssssssssss
