Adding a donation button to your blog
I was asked how to add a donation button to a blog. PayPal makes this very simple, by providing a button builder that produces a complete chunk of code for you to copy and paste.
In PayPal use Merchant Services > Accept Donations.
Take the code produced and make sure you choose HTML mode in your blog editor. Paste the code in, and publish. The success, or otherwise, of your edit will depend on what elements your blog host allows you to embed. Blogger, for example, will work fine. Tumblr won’t. If you want to do something similar in Tumblr you’ll need to host the button elsewhere and link to it, as I have there.
