PayPal button appearing too small
If you have tried adding a PayPal button into a Joomla article but it has displayed, on your site, too small - this trick is for you.
The code that you copied from PayPal will look something like this:
<form action="https://www.paypal.com/cgi-bin/webscr" method="post" target="_top">
<input type="hidden" name="cmd" value="_s-xclick">
<input type="hidden" name="hosted_button_id" value="GQT7EVE65B7NG">
<input type="image" src="/https://www.paypalobjects.com/en_US/GB/i/btn/btn_buynowCC_LG.gif" border="0" name="submit" alt="PayPal – The safer, easier way to pay online.">
<img alt="" border="0" src="/https://www.paypalobjects.com/en_GB/i/scr/pixel.gif" width="1" height="1">
</form>
To increase the size of the PayPal button on your site, just change the code to
<form action="https://www.paypal.com/cgi-bin/webscr" method="post" target="_top">
<input type="hidden" name="cmd" value="_s-xclick">
<input type="hidden" name="hosted_button_id" value="GQT7EVE65B7NG">
<input type="image" style="height:47px;" src="/https://www.paypalobjects.com/en_US/GB/i/btn/btn_buynowCC_LG.gif" border="0" name="submit" alt="PayPal – The safer, easier way to pay online.">
<img alt="" border="0" src="/https://www.paypalobjects.com/en_GB/i/scr/pixel.gif" width="1" height="1">
</form>
The only change is the addition of style="height:47px;" on the fourth line. Add it in to your code, save the article and see if it has worked for you.
