Linked images border

Hi, firstly I would like to congratulate this theme, wich is very flexible to edit. The css thing that was done, like... separate the files by categories (graphics, layout, links...) was a smart move dude.

But there's something that I couldn't change at all: the freakin border that appears on linked images.

I've tried a lot of stuff, since changin the system's default.css to all the css files inside the theme folder. Here's what I've tried:
Note: The value of property border has been tested with "0", "0pt", "0 none", "0pt none" and "hidden".

img, a img, a:link img, a:visited img, a:hover img, a:active img, .inline img{border:0;}

I've tried this in every freakin css file inside the theme folder, nothing happened. I've even tried to put an inline code into a block that I've created, like:

<a href="#"><img src="#" style="border:0"></a>

and

<a href="#" style="border:0"><img src="#"></a>

I just couldn't make it and I've ran out of ideas.
You know... it isn't something that will ruin the site or I'm gonna die if it doesn't get fixed, but it's kind of annoying. Especially when you're gonna rate a node with the fivestar module. You may take a look at the attached image.

Anyway... thank you guys for reading.
