There's not a way to do that built-in to the SCLogin module. The SCLogin module supports a text or standard HTML button for the "Login" button. To use a graphic, you'd have to make a minor modification to our template files in the SCLogin module to do what you're looking for.
The edit to make is in the /modules/mod_sclogin/tmpl/login.php file. Around line 28, you'll see:
echo '<div class="sourcecoast sclogin-modal-links sclogin"><a ' . $loginClass . ' href="#login-modal" role="button" data-toggle="' . $modalName . '">' . JText::_('MOD_SCLOGIN_LOGIN') . '</a>';Change that top line to:
echo '<div class="sourcecoast sclogin-modal-links sclogin"><a ' . $loginClass . ' href="#login-modal" role="button" data-toggle="' . $modalName . '"><img src="link-to-your-file.png" /></a>';
I hope that helps, but if you have any questions, just let me know!
Thanks,
Alex
