Would like to add a pdf to the web-site (our new brochure) but not where I can upload it as it will not recognise it in the image library.. any ideas..
You can use the generic file browser which can be accessed from The Edit Website > Customize Template CSS section when managing your site. Once there click the select file/image button to load the file browser. Once uploaded you can select your file and it will take you back to the Customize Template CSS page with the URL path of the file showing. You can copy that URL and use it in the website pages editor to link to your PDF.
