<form action='samepage.asp' method='post' name='foobar_form'>
<input type='image' src='somepath/image1.gif' name='e_foo' value='bar1'>
<input type='image' src='somepath/inage2.gif' name='x_foo' value='bar2'>
</form>
clicking on the first button will result in a postback with no data.  If the
method is 'get' it works.  The 2nd button causes a postback with data.  As far
as I can tell it's only names starting with 'e_'.  Any other name seems to be
fine.  Also does not depend on order (first last, more than two <input>s etc)

Reproducible: Always

Steps to Reproduce:
1. create page with a method=post form
2. create <input type=image name='e_foo' value='bar'>
3. write some code to query and display form data
4. browse to the page
5. click on the image
6. observe lack of form data

Actual Results:  
in asp:
at the top of the page I have:
response.Write Request.Form.Count
Response.Write "<BR>"
for i = 1 to request.Form.Count		
	response.Write request.Form.Key(i)
	response.Write " = "
	response.Write Request.Form.Item(i)
	response.Write "<br>"
next

A '0' is displayed at the top of the page after clicking on the image button

Expected Results:  
If the image name is change to 'd_foo'
3
d_foo.x = 13
d_foo.y = 10
d_foo = bar

IE 6 and Opera 7.54 exhibit the same behavior.
If it's intentional, it's a pretty good job of boog compatability!
"e_"  or "&e_" ("pi_" or "&pi_" also) is special number representation in some
scripting languages.
Isn't it has relation to your problem?
What will happen when second INPUT's name is changed to "pi_foo"?

I tried to check this, and now can't reproduce the behavior at all.  I had a
simple test case that failed on three browsers, but now works on all three. 
I'll keep trying, but for now it's certainly unconfirmed.
This is an automated message, with ID "auto-resolve01".

This bug has had no comments for a long time. Statistically, we have found that
bug reports that have not been confirmed by a second user after three months are
highly unlikely to be the source of a fix to the code.

While your input is very important to us, our resources are limited and so we
are asking for your help in focussing our efforts. If you can still reproduce
this problem in the latest version of the product (see below for how to obtain a
copy) or, for feature requests, if it's not present in the latest version and
you still believe we should implement it, please visit the URL of this bug
(given at the top of this mail) and add a comment to that effect, giving more
reproduction information if you have it.

If it is not a problem any longer, you need take no action. If this bug is not
changed in any way in the next two weeks, it will be automatically resolved.
