Knights and Merchants.net Forum

So I often see people "hiding" their links under words like "click here" for example. So instead of the link, you see click here and it sends you to the page.
I've seen this for years but I never knew how to do it. Any help please?

One more: how do I make a picture appear in a post? Again, something I've seen forever but lacked the knowledge needed to do it myself.

Thanks
