Custom html rule set doesn't work properly

[Opossumi]

I use Snippet Master in my client's web site, and it works mostly fine. But there's one thing that I don't understand...
There is a problem with images. I have set css to make a border in all images in the content div. (It's 1px solid black.)
But when my client adds a photo to the page, the result code Snippet Master do is: img border="0" alt="xx" width="xx" and so on....
I use custom rule set, and there is: img[class|src|alt|title|width|height], so there shouldn't be any border -attribute.
Or maybe I'm understanding something wrong. How can I disable making any html border attributes to the images?
Thank you very much

I just want to confirm the problem.

You are saying that the border attribute is being added to the IMG tag, even though you have not specified it in the customer rule set?

Is this correct?

[admin]

When you are adding an image in the wysiwyg popup window, is there any value defined in the "border" field?

Yes.

I'm not sure, what there is in border field, when my client adds an image. But now there is zero in final html. In fact, I tried to remove border setting manually in wysiwyg, but nothing happened. Border attribute stays. I thought that the rule set and (x)html cleaner in wysiwyg editor would remove those unvalid markups.

Does this messy explanation help?

The border attribute is valid xhtml markup.

Can you send me a link to your SnippetMaster installation URL, and a username/password?  I will try to recreate the problem and see if I can find out what is the way to stop the unwanted border attribute from being added to your code.
