[Lazarus] How to assign a image file for a variable as Blob

[Johan Tu Toit]

Hi all,
Please I tried the above statment:
DataModuleConn.SQLQuery.Params.ParamByName('getPHOTO').AsBlob:=image1.Picture.LoadFromFile(OpenPictureDialog1.FileName);
its giving error:
image.pp(358,155) Error: Incompatible type for arg no. 1: Got "untyped",
expected "AnsiString"
image.pp(400) Fatal: There were 1 errors compiling module, stopping

The type assigned its wrong.

Thanks
