CMS large images

[Oclamora]

Hi y'all,

I added a large image using the bbcode [IMG] tag to an article.
The article contain only one image, and the section contain only that article.
I setup the article to "Full Display in Section Page".
The image is %100 fit to the screen in the article; however, in the section the
image goes back to its original hight and width. Which make the image goes out of boundaries.
My questions are, is this a bug? if so, will it be fix in the next release? and how I can fix it?

Thank y'all for your help in advance!
