hey guys I want to implement a "donate with bitcoin" button into my site. what is the current most easy-for-user way of doing this?

Here's a related thread:

If you are looking for a tipping system, similar to flattr, you might consider adding a YouTipIt "junket" badge to your site.  For example:

 

Watch out for scams to steal your bitcoins as you spend/donate it  http://evilpacket.net/  (Is this vulnerability fixed now?)

One possible solution :
If the bitcoin client supported a standardized text block containing the address & amount, eg.
BCAddress=12hFuVrSpLaPeTxwGUoPXoTDuhFnDhxRu3,Amount=1.5BTC

then you could have a "Copy to Clipboard" link, paste it in to the bitcoin client, and click Send. Would make BTC easier to spent, as you wouldn't have to write in the amount.

Don't know how secure this is though, maybe someone can write a web script to snoop the clipboard buffer?

Try https://bit-pay.com and click on the Charity icon. We have lots of easy options!
