Is it possible for wall feeds shown on ones website to make the picture and the text float left ? Right now the text is above the picture which takes up a lot of space....

You mean the media picture will be left and post text will be at right side? this kind of layout was not followed, if you see post in facebook, it's same as what wall feed post layout look like, also if picture size set to full for the layout you suggested then layout will be almost same as current one. But customization possible on request. If you set picture size as small then picture will float left to house the media description text at right instead below.

Yes, I mean media picture left and post text at right side - and everything else underneath this. How much would that cost to get customized??

After updating the module to the latest version, this alteration with the image to the left does not work anymore !!??

Fixed it myself with CSS!
