interbase + php

hi all!! i have the problem that i want to put an image into a firebird database. the problem is that when i copy the code of the image into my sql syntax, the code contains ' and " and then php thinks that this is the end of the sql statement, although this is just data of the image. is there another method how i can put images into a database??? what are the functions ibase_blob_create good for?? many thanks greets markus
