I believe msalum is not comfortable with reading/writing English, and wants to insert screenshots to explain a problem, and that this thread should explain how.
BTW, I do not get any "attachment" when clicking Additional options, only

I have tried to upload to a sharing site like photobucket earlier, and post the URL. On click I was then transferred to an external window cluttered with ads. I have seen some users here inserting thumbs that expand on click. Neat trick and much better than a new window with ads, but could anyone explain how to do that?
