Hi Margaret – I’m guessing the software was ‘dreamweaver’… this is somethign for making it easier to change/author html websites. However it’s a bit specialist nowadays, and difficult compared to wordpress etc.
If you drop me an email on firstname.lastname@example.org I would be happy to help you change/remove this image (without charge). You will need to provide me (or an other) what’s known as FTP details in order for them to be able to make changes. Do you have these. There are 3 elements – the FTP address, a username and a password.
Kind regards, Toby
