Enrolment

hi this can be done by modifying the source code ... in your main directory go to look for enrol.html

it should be

moodle directory /enrol/paypal/enrol.html 

in this file you will see 

<p><img alt="xxxxxxxx" src="..hxxps://www.paypal.com/en_US/i/logo/PayPal_mark_60x38.gif" /></p>

change the link to any image you want .. and job is done )
