Images in forum signature still not being displayed?

[ToTheFuture]

I posted this in my CSS to remove signatures:

Code:

.signature_div img{
display: none;
}.

When I edited my signature, I added:

Code:

img[src="URL"]{  display:block !important;  }

This was to show the image url.

But still, I would get my signature showing up like this:


As you can see, the code still did not unblock the image! :\ Help? Thank you!

Hi, the CSS code you used to block signatures cannot be 'unblocked' by using what you've posted in your signature. The code you've used in your signature is CSS and as far as I know, that doesn't work there!

Thank you for answering. I found that here, and it worked a few months ago then took it off. Now it does not work anymore?

EDIT:
Okay, now not even the code will show up, or anything I type as a signature?

EDIT AGAIN:
Is there any way that every image will be blocked except for one or certain images? That can work.
