image input element types in form -problem

[seanos11]

Hi,

I am having a problem with image input elements within a form.

this is a portion of my code:
<form action="./searchServlet">
<img src="../images/search.gif" alt="" width="43" height="16" border="0"/>
<br/>
<input type="text" name="q" size="11" class="box"/>
<br/>
<input type="image" src="../images/search.gif" name="web" class="submit" value="Web-Search"/>
<input type="image" src="../images/picsearch.gif" name="picture" class="submit" value="Pic-Search"/>
</form>

It is a textbox with 2 input image 'buttons'. The intention is to pass the content of textbox q as a web or picture search, depending if the user clicks the web image or picture image.

This works fine on web-browers (Firefox, IE) and most phone devices, clicking 'web' search the GET request contains:
q=xyz&web.x=17&web.y=10&web=Web-Search

But clicking 'web' search using a Nokia 6600/7610 or Nokia Toolkit browser the reqest contains:
q=xyz&web=&picture=

So, is it possible to solve the above problem without having to make the 2 input elements type="submit", I would like to leave them as type="image".

There was a similar post before but the 1 response had no solution.
