Problem with Opera in Turbo Mode

I checked one of my projects (fixed layout) in all the major browsers and in different resolutions. All looked good.

But I noticed that in Opera (ver 11.10) when the turbo mode is engaged, the website is not rendered properly. When turbo mode is off, everything looks great.

Not sure if this can be corrected since everything is good in IE, Firefox, Chrome, & Safari. Besides, Opera is not considered one of your most popular browsers used.

Anyone have this problem with Opera in turbo mode (you can find the turbo switch in the lower left corner of the browser)?

I discovered that:
When Opera Turbo is enabled, webpages are compressed via Opera's servers so that they use much less data than the originals. This means that there is less to download, so you can see your webpages more quickly.
This includes images, so maybe I need to look into this more.

My other websites don't problems with Opera in turbo mode.
So could be type of images I use (GIF, PNG instead of JPG).
