Answer 1

Try:

Dim ms as MemoryStream = New MemoryStream(img)
Dim bmp as Bitmap = CType(Bitmap.FromStream(ms), Bitmap)

bmp.Save(@"C:\images\name.gif", ImageFormat.Gif);

bmp.Dispose()
ms.Dispose()

The easiest way is to use File.WriteAllBytes

Dim img as byte()=dr(0)
File.WriteAllBytes("C:/images/whatever.gif", img)

Answer 3

System.IO.File.WriteAllBytes(@"c:\whatever.txt", bytes)
