I'm using Wordpress, is there some type of code I can enter into my style.css to make sure all images are aligned centre. Some posts, like this one: http://dev.wegotthiscovered.com/news/20-minutes-gameplay-footage-dead-island/ align them to the left. I have over 3000 posts and I can't go into everyone and manually do it. Here is my current style.css http://dev.wegotthiscovered.com/wp-content/themes/continuum/style.css
Do you have a css class name for each image you want to center? For instance, in the example you link to they have aligncenter as their class name. Now with that you can have text-align: center; (for IE) and margin: 0 auto; (other browsers). If you don't have class names for each of them, there's a way it can be done with a database script all at once.
