Need Affiliate LInk Help

i know how to insert an affiliate image link . . . but when the image appears in the preview page, it has moved all the adjacent text down to the bottom of the image. how do i get the image to line up next to the image on the top left side of it? if i upload a screenshot of the same image it does not move the text down, it lines it up properly. i don’t see anything in the html to cause this and it happens on any affiliate image link.

i hope i explained that well. any suggestions?

thanks.
