Hide image of specific size, by CSS?

Question

Thanks in advance for your help!

I have an RSS, I want to post the content of this RSS on my page, but the RSS is from WordPress and it contains an image of a button

Answer 1

the comment button URL is sequential, so even if I could hide "wordpress.com/commentbutton/12", the next button url is "wordpress.com/commentbutton/13" and so on :(

CSS can actually help out here. The attribute selector can select attributes which contain a value. So, this:

img[src*="feeds.wordpress.com/1.0/comments"] {display: none;}

should do it.
