Problems with Image Align and CSS Styling

I am having a problem with images being aligned on on the Zenlike theme (http://www.freewpthemes.net/preview/zenlike)

I want to style the images using class=”alignright” and class=”alignleft” but it’s not working and I can’t find out my!? It will align left and right but will not style using the stylesheet. If I create a link around the image, it always leave the border as the stylesheet doesn’t include img styling by default.

I have added this simple bit:

#sidebar img
{
border: 0px;
}

This removes the coloured link border around the top image in the sidebar, for example. But I can’t apply any other styling anywhere else in the document.

You can see what it does by default here: http://www.celtic-irish.co.uk/festival/ on the top image in the post/page.

I have tried adding img { border: none;} img { border: 0px;} but nothing works.

I’m added this img { border: 6px } just to illustrate that it isn’t working because it isn’t changing the border.

I’ve also tried img.alignleft etc… am I doing something wrong?

Obviously, I also want to add padding depending on whether it is left or right and that also doesn’t change when I update the stylesheet.

One further note. When wordpress adds the images it adds them with the class=”alignright size-medium wp-image-16″. Is there some other styling in play?

Please help, many thanks
