Ok see up above of where you type your response? See where it says Font, Size, Color? Then below it should say B for bold, I for italics, U for underline, then it gives centering options for your text etc., next in line should be a square box with a yellow background with the Mt. and the Sun. That is the one you click for uploading the pictures. Try again, if you need more help just let me know.
Edit to add you can also add a link to your photobucket account, we can click the link and view your pics.
