SQL & PL/SQL

Hi,

wanting to test a report tool to check it shows signature correctly which will be passed to us as blob but not got any real data yet.

Trying below
blob table 2 columns
employee number, image_signature.
insert into blob table values(2, hextoraw('C9CBBBCCCEB9C8CABCCCCEB9C9CBBB'));

Anyone know/have example hex of simple image ideally signature squiggle or similar just a pic of some sort can check if gets blob data inserted correctly.

Not sure of any other way we could insert test bob data?

Thanks
