[Paypal checkout / Matrix] button confusion

I'm using both Email Checkout and Paypal Checkout modules.
Many of my customers are clicking the Email Checkout button when they actually wanted to pay by credit card.
I think the confusion is that the paypal button just looks like some sort of logo and very different from the standard grey buttons that they used to get this far along in the ordering process.

Is there a way to replace the standard Paypal logo/button with one the looks that same as all the others but clearly states [CLICK HERE TO PAY BY CREDIT CARD] or something else blindingly obvious

Thanks alec - The paypal button is pretty obvious to those who know what paypal is Unfortunately many of the people in this country (NZL) do not. Those who are new to online shopping and struggle with even the most basic procedures.
Sometimes I wish I could just tell them to 'go ask a 12yr old to help you" lol.

In modules/checkoutpaypal/templates/ the bottom of the PaymentButton.tpl file we have:

<div style="width:200px">
<input type="image" src="http://{$payment.paymentVariables.ppurl}/{g->text text="en_US"}/i/btn/x-click-but01.gif"
name="submit" alt="{g->text text="Pay with PayPal"}" />
<input type="image" name="submit" alt="{g->text text="Pay with PayPal"}"
src="{g->url href="modules/checkoutpaypal/images/"}logo_ccVisa.gif" />
<input type="image" name="submit" alt="{g->text text="Pay with PayPal"}"
src="{g->url href="modules/checkoutpaypal/images/"}logo_ccMC.gif" />
</div>

I have tried changing the top src= line to show a button I've placed in modules/checkoutpaypal/images but that changes nothing in the website.

I cant see any info in the top of the file about modifying it..

This is the whole file:

{if $payment.paymentVariables.orderTotal > 0}

</div>
</form>
{/if}

I do not have that info in the top on my file, so I can only assume its been removed. (I'm not the only person who has worked on this site Having said that, I do already know about using /local/ directories for modified files, and did use one thanks.

Assuming that changing the top src= line is still the right thing to do to change the button, I will try again with the cache cleared.

Thanks.
