You get my upvote for the honesty. YOu can contribute anyway you want. Post some of your writing if you want. You could write articles about the economy or about managing money, it is all up to you.
P.S you insert images by just pasting the link to them. You need to make sure the page only has the image on it though , so if it is on a page with other stuff, right click it and hit view image in new tab.
