Hi

I agree and also think of a Picture.ToString-method which provides a 
string representation of a bitmap file. The conversion routines proposed 
so far do something different. The following function is based on the 
one used by Bruce, but it utilizes a virtual file system located in the 
RAM instead of the physical hard-drive:

Public Sub PictureToString(Pic As Picture, sFormat as String, Optional 
iQuality as Integer = 100) As String

      Dim sPath As String

      Shell "echo $XDG_RUNTIME_DIR" Wait To sPath
      sPath = Trim(sPath) & "/tmppic." & sFormat
      Pic.Save(sPath, iQuality)
      Return File.Load(sPath)

End

I can imagine that an according picture/image-method for this would be 
useful particularly if it would be quicker.
