Graphics problem with Opera Mini simulator

[Also posted online as:

I'm having a weird issue with graphics not appearing in Opera Mini
simulator that I hope someone here can help me with.

The site in question is http://mobilewtnh.com.

Along with a favicon, there is supposed to be a logo graphic at the
top of the page. I can see my graphics if I load the site on a
desktop browser or on other devices like Razor and Q, but not Mini.

The odd thing is I am adapting the code from a co-worker's site,
http://live8.com and their graphics work fine in Mini. * 

Also, I can see my graphics if I load the site on a desktop browser,
and I get the graphic if I call up the image address directly in
both Mini and on the desktop.
<http://mobilewtnh.com/logos/mobilewtnh100.gif> or
<http://mobilewtnh.com/logos/mobilewtnh100.jpg>

Is there something weird with my graphics and the way they are
saved? Can Mini only handle certain types of gifs and jpgs?

Thanks in advance for any leads to this problem.

* The php script does an if else to see whether a particular device
can read jpgs or gifs or pngs. You can see that bit of code at
