<p>I have a GIF image that has an alpha set, and when my site loads in Firefox 3.0, it acts transparently on the parts of the image that should.  However, when I try to load the GIF image in IE7, it comes back as a solid block.  Actually, it is like the color from the image bled into the transparent area.</p>

<p>Do anyone have any suggestions for resolving this kind of problem?  Pointers on what to look into, or a route you've used to solve this kind of problem.</p>

<p>I've been controlling this in CSS -- and while I'd like to avoid the conditional comments route and multiple CSSes, I'd be willing if the suggestion tangibly shows how I can resolve the IE compatibility problems.</p>

<p>Thanks,
Sean</p>

Try these two -- mess with the numbers until you get it right. i 4get which is for IE and which is FF/chrome
```
```
opacity: 7;
filter: alpha(Opacity=7);
```
```
