Hi, normally to view attachments you have to be logged in. If it's a photo then it should be visible in the comment and you just click on it to expand. If it's a link to a website it should be possible to just click on the link (
http://www.blablabla) and it will open a new tab on your computer to the website. What are you usually using, a computer, tablet, phone etc and which system - windows, apple, android?
Just ask if you need more info, I'm used to helping my misses and mum etc so there are no daft questions!
