Rich Text Box - Program That Will Read From Various Text Files (preferably RTF Files)

Im designing a program that will read from various text files (preferably RTF files) and then put them into the RTF box in the program when a button is clicked.

Here is the portion of my code that i am referring to.

Try
Dim fileText As String = My.Computer.FileSystem.ReadAllText("c:\" & selectedHero & ".rtf")

infoDisplay.AppendText(fileText)
infoDisplay.Rtf.Format()

Catch
MsgBox("Selected Hero currently has no File with us.")
End Try

Now heres the problem. In the file i have a few pictures and its formatted and what not. I thought since its a RTF file and the Box is RTF it would auto format.... but anyways. It appears like this in the RTF Box.

{\rtf1\ansi\ansicpg1252\deff0\deflang1033{\fonttbl{\f0\fswiss\fcharset0 Arial;}}
{\*\generator Msftedit 5.41.15.1507;}\viewkind4\uc1\pard\f0\fs20{\object\objemb{\*\objclass Paint.Picture}\objw3000\objh3000{\*\objdata

[CODE]...

Ok so im not sure how i can read from a RTF file and put it in the RTF box with the right format....Ive been searching around for a while.
