Some say that a picture is worth 1,000 words, but regardless of how you do the math, it's fair to say that a good photo can say a lot more than 140 characters. With that in mind, Twitter is giving greater emphasis to photos within tweets by placing them front and center in the post, with the actual tweet serving as a simple caption below. Looking at it now, the decision seems an obvious one, but all photos were previously smaller and subservient to the short text. The visual redesign applies to both landscape and portrait photos, so regardless of how you frame your image, you can now let your shooting skills do the talking for you.
