How to attach pix to forum post?

YaBB Help mentions an Attach button but darned if I can find it. Yet lots of posts have images.
Thanks for the help.

the post that have images are linked to other websites, I use my own some use like photobucket etc

I am pretty sure the attachments are disabled on this install

An update: I did wonder if (as Osgeld suggested) Attachments are disabled for Arduino forums. For reference the Insert Hyperlink does work (the 'url' tags), but Insert Image (the 'img' tags) gives the "bad / gone image" icon (the red X) rather than an inline image.

the img tags work fine if you point it to a type address

Yup. You just have to host it somewhere. is good if you don't want to have to sign up.
