BLOB insert into HANA Problem

I am trying to insert an image into HANA using the BLOB data type. I am creating a procedure then calling it to do the insert, but when I go to look at the data preview, the BLOB has been changed to something completely different and I dont know why(see pic). I have attached my SP and call statement. I would really appreciate some help on this. We're scheduled to display this funcitonality at FKOM.
