SOLVED (Although I am not sure how)
Anyway, I would appreciate orientations about the cover images. For instance, is it possible to alineate the text under the cover image with the image itself? It seems to me that if the image is not clearly rectangular, the text won't match with the limits of the image, e.g. http://www.postconvencionales.org.ve/index.php/ethikos/index
Or is there some way of fixing this that I'm not seeing?
