If your wordpress blog is .com hosted, and you find yourself using a predesigned theme you may also find you wish you could change some things.
My theme has preset icon borders for all the images in the theme. When I attempted to add RSS feed icons or twitter icons to the sidebar, the icon border followed over and it looked awful!
I have devised a way around the this problem. If you insert the image you want to use (even if you want a link attached to it) you can use a Text box which is for text and HTML to erase the style for the borders with the following code:
<a href=http://twitter.com/tarinae><img src="http://putyourtwitterpiclinkhere.com" border="0"></a>
That will not only post an image but will give the image a direct link to the page. That can work for any image/link even mailto:.
Thought I would share.
