I have something like the following code:
<div style="border:2px black solid;overflow:hidden;">
<span style="float:right;">
<img src="sprintlogo.png" alt="Test Image 1" />
</span>
<img src="sprintlogo.png" alt="Test Image 2" style="float:left;" />
<p>Test Text</p>
</div>
For some reason, the bottom border around the <div> is not flush with the images, etc. For example, we get things like this:

It’s not an issue with the images or anything (i.e. there is no whitespace in the image file).
By adding background-color:blue; to the <span>‘s style attribute, we can see that the span seems to be taking up extra space.

I tried messing with the span’s margin and padding to no avail. Does anyone have an idea of what is going on?
Very strange indeed.
I found that by removing the span and simply floating the image right it removes the extraspace. Indicating the issue was in the span.
Then I looked at firebug and found that the extra space was rendered height.
Apparently the space is being creating by a stray character (which is odd because the character is still there if you remove whitespace…), as demonstrated here where I turn font-size to 0 and the space goes away.
Edit
Yeah the issue is most definitely that the image is being positioned assuming there is text and aligning it with the imagarinary text (
veritcal-align:baseline;) another fix would be to align the image with the bottom of this text here.
