Yeah like in my thread it has the donate button ill explain what to do.
On paypal make the donate button right then on the image right-click -> save as -> save it as whatever.
Go to a uploading image site such as (tinypic) -> browse -> Upload. Copy/Paste the Code in the thread.
Then go back to the paypal button page copy the "E-Mail" link code -> Click the "insert link" on sythe on the actual image you pasted, paste the code. Click on. Then click "post quick reply", and your donate button will be there fully working.
