[ic] Images instead of Form submit buttons

[Zachary Matthews]

I have seen this question on archived mail lists, but I have not see it 
successfully answered.  Please advise!

I am using images instead of the standard form submit buttons.  I keep
running into problems trying to set mv_click and mv_check, and I have
tried all kinds of solutions to no avail.  Has anyone solved this
problem?

Here is what works:
<input type="submit" NAME="mv_check" value="Log In">

[set Log In]
[if session logged_in]
mv_nextpage=index
[else]
mv_nextpage=login
[/else]
[/if]
[/set]


Here is what I want to do (none of these attempts successfully set
mv_check):

A)
    <input type="image" src="submit.gif" name="mv_check" value="Log In">

B)
    <input type="hidden" name="mv_check" value="">
    <input type="image" src="submit.gif"
onClick="this.form.mv_check.value='Log In'; this.form.submit();">

C)
    <input type="hidden" name="mv_check" value="">
    <a href="javascript:void 0" onClick="this.form.mv_check.value='Log
In';  this.form.submit(); return(false);"><img src="submit.gif"></a>
"


D)
[button
  text="Log In"
  src="submit.gif"
  hidetext=1
  form="logform"
 ]
 mv_check="Log In"
[/button]

E)
[button
  text="Log In"
  src="submit.gif"
  hidetext=1
  form="logform"
 ]
    [if session logged_in]
    mv_nextpage=index
    [else]
    mv_nextpage=login
    [/else]
    [/if]
[/button]


I am running out of ideas... and starting to run out of hair to pull...
please help!
Thanks.
