If you'd like to store binary data, such as an image, in MSSQL, it's common to have problems with addslashes and co.
This is because the MSSQL parser makes a clear distinction between binary an character constants. You can therefore not easilly insert binary data with "column = '$data'" syntax like in MySQL and others.
The MSSQL documentation states that binary constants should be represented by their unquoted hexadecimal byte-string. That is.. to set the binary column "col" to contain the bytes 0x12, 0x65 and 0x35 you shold do "col = 0x126535" in you query.
I've successfully stored and retrieved jpeg images in a column with the "image" datatype. Here's how:
// storing a file
$datastring = file_get_contents("img.jpg");
$data = unpack("H*hex", $datastring);
mssql_query("insert into images (name, data)
values ('img.jpg', 0x".$data['hex'].")");
// retrieving
$result = mssql_query("select data from images where name = 'img.jpg'");
$row = mssql_fetch_assoc($result);
header("Content-type: image/jpeg;");
echo $row['data'];
As you can see there is nothing to do with the image on they way out, just blurb out the buffer your recieve as with any other field type.
