Convert image datatype to varchar

I have a table Table1 which has a Col called "Msg" datatype image<binary>. Msg alreay has the plain text or RTF text as a image datatype (binary)
If I execute the following query "Select Msg from Table1 where id =3" then this query is returning the following ASCII/Binary data.
Msg = "0x7B5C727466315C616E73695C616E7369637067313235325C64656666305C6465666C616E673130333
37B5C666F6E7474626C7B5C66305C6673776973735C66707271325C6663686172736574302041726961
6C3B7D7B5C66315C6673776973735C66707271325C666368617273657430204D6963726F736F667420"
Can any body tell me how can I convert the above binary data to plain text from my query?
Thanks for any reply.
There is no Conversion of Image to Varchar but you can convert Image to Varbinary with limitations, the text below is from the BOL( books online).
Automatic data type conversion is not supported for the text andimagedata types. You can explicitly converttextdata to character data, andimage data tobinaryorvarbinary, but the maximum length is 8000. If you attempt an incorrect conversion (for example, if you convert a character expression that includes letters to anint), SQLServer generates an error message.
Hope this helps.
