I'll keep this brief for now… I have no idea what this problem could have to do with, so I'll withhold any actual code until someone points me in a direction.
I have a website. This website has some images. All but two of these images display fine in any browser. Two of these images display fine in every browser EXCEPT Firefox. My only lead is this: looking at the two elements in Firefox's "tools", I notice that both elements have been assigned the class "wmwfsqbhwdmaytbjhpmp". Same gibberish for each element. As you can probably tell, I didn't put that there. Seems likely to be related. Maybe it isn't though.
So… do you need my css? My HTML? Could this be a browser issue? I'm a relative beginner to all this, so please bear with me, and please point me in the right direction.
Thanks.
EDIT: Here's the html…
<header>
<div id="logo">
<img src="images/main/logoText.png" alt="logoText">
</div>
<div id="bannerAd">
<img src="images/main/topAd.jpg" alt="bannerAdTemp">
</div>
<div class="clear"></div>
To repeat: logoText.png displays fine in any browser, topAd.jpg displays fine in any browser except Firefox. topAd.jpg is the one with the gibberish class applied. Nowhere do I apply classes to it with jquery or anything like it.
