Watermarks not appearing/displaying correctly when installing plugins

Hi there,

I am building a site for a client to display all of their stock photos. We seem to be having problems installing watermark plugins – when they are installed, the watermarks are not displaying correctly on the photos – they are not appearing at all. At the moment, the plugin I am using is called ‘Image Watermark’ by dFactory, but I have not had success with any other plugins either.

I would appreciate some guidance and help with the above – as this is proving frustrating for both myself and my client!

Thanks,

Robert.
