IE8 vs Firefox 3.6.13 display of jpg files different

The “printing” (not text) in the jpg file being displayed on my website both show clearly in IE8 but is garbage in Firefox. I am using the "printing" as a tool to diagnose the problem. The issue is not text display but resolution; both browsers are displaying the same file. Since I am programming this html code I have enlarged what is displayed to no avail. What can I do to my Firefox browser to fix the problem?

Can you post a link and attach a screenshot to show your problem?

The problem partially goes away after talking to a friend. With Firefox, if I successfully push ctrl++ the "text"slowly becomes readable as in IE8. This must change the resolution of what is being displayed in Firefox. But the jpg picture is taking more of my monitor area to show this than what is needed with IE8. I do not understand...

You are downscaling those large (5000px) images quite a bit. Firefox still doesn't do downscaling very well, so it it better to do the scaling yourself and serve images in the resolution that you need.

OK I did some experimenting. Starting at 100%, I created 50, 40, 30, 25, 20 and 10% files for testing. The resolution degraded but the "text" improved. At 20% the resolution was too poor. I have deleted all test files on my test webpage. The original and 25% is there. You can see the results. Now go and look at it with IE8. Clearly (pun intended) the rendering is still much better. I assume this is a bug in Firefox and eventually will be fixed? Rick
