I've tested this with IE 5.5 SP1 + Q299618.
Here are the results:

Two randomly chosen gif and jpg images were renamed to gif.txt and
jpg.txt respectivly.

TEST 1.
Trying to open images with File -> Open my notepad.exe is spawned and
displays the "content" of the images.


TEST 2.
Created a test.html document with links to the images:
<HTML>
<BODY>
<A HREF="gif.txt">GIF</A> <A HREF="jpg.txt">JPEG</A>
</BODY>
</HTML>

The "content" of the images were sucessfully displayed in the IE
window.


TEST 3.
Used the <IMG> tag to embed the images in the html page:
<HTML>
<BODY>
<IMG SRC="gif.txt"> <IMG SRC="jpg.txt">
</BODY>
</HTML>

Image placeholders were shown, but no images (wrong MIME type
according to extension).

TEST 4.
Renaming test.gif -> test.html and opening it in IE is displaying
parts of the image "content": GIF89aL9³ÿÿÿÿÀÀÀ óó+}|??/E;


MY CONCLUSION:
I couldn't reproduce what you experienced in IE 5.0, so I suppose
that this issue has been corrected by Microsoft (either in 5.5 or 5.5
SP1).

Thnx for your time  :)
