Cannot center image

Hi all,

I am very new to wordpress so sorry in advance if this is a stupid question, but I tried to took it up elswhere but could not find the answer, and there seem te be more people with the same problem.

The thing is, after I have made an image with a hove text and I paste the shortcut in the visual editor, it does not center.

I tried:
<p style=”text-align: center;”>[image-caption-hover id=”1″]</p>

As well as:
<div style=”margin-left: auto; margin-right: auto; width: center;”>
[image-caption-hover id=”1″]</div>

And both did nothing.

Also tried to make the left and right margin 30% (with width on “auto”), and this does work but then the image is smaller in size.

In the end I managed to get it with, it still got the image smaller but it was the best I could do:
<div style=”margin-left: 25%;margin-right: 25%;width: 50%;”>
[image-caption-hover id=”1″] </div>

There must be another and better way to do it right?
Can someone please help me? Thanks!
