Why? And, importantly, what do you use: System.Drawing? WPF? Something else? In all cases, read on imaging there; everything else is explained.

If you use System.Drawing, you can try this code

Imports System.Drawing
Imports System.Drawing.Imaging
 
    Public Shared Function GetBinary(ByVal image As Image, ByVal format As ImageFormat) As Byte()
        Using ms As New System.IO.MemoryStream
            If (format Is Nothing) Then
                format = image.RawFormat ' use image original format
            End If
            image.Save(ms, format)
            Return ms.ToArray()
        End Using
    End Function

Example:

Dim binaryArray As Byte()
' Get image from PictureBox and GetBinary (use original format)
binaryArray = GetBinary(PictureBox1.Image, Nothing)
 
' load image from file and GetBinary (formatted to png)
binaryArray = GetBinary(Image.FromFile(sourceImageFileName), ImageFormat.Png)
 
' To save current binaryArray to image file:
System.IO.File.WriteAllBytes(destinationImageFileName, binaryArray)

You can search for articles in the search box above. Like Convert Image File to Bytes and Back [^], for example.

No, there isn't. Why should there be - that looks straightforward to me.
