I recently lost my computer (long story) so I've had to do EVERYTHING on my phone. I was working yesterday and trying to create a tab for my business FB page. I'm trying to center a picture but of course when I touch the picture to grab it, the whole page moves as opposed to just the picture. I tried to find an app that would let me use a mouse like on a computer, but no luck. I'm sure I'm over looking something here... how do I get my image centered???
