Solution
You need use redirects.
Source of Donate button
[**](http://Kristinita.ru/Donate-files/Bitcoin-Redirect)
If you click the image, you will go to a page http://Kristinita.ru/Donate-files/Bitcoin-Redirect. See answer on Meta Stack Exchange, how use Markdown markup for this construction. Alternative worked HTML source:
<a href="http://Kristinita.ru/Donate-files/Bitcoin-Redirect"><img src="http://Kristinita.ru/Donate-files/Bitcoin-Donate-button.png"></a>
Source of Bitcoin-Redirect page
<script>
window.location.href = "bitcoin:1DF9jgzftTFn4ZnDV2YEjUtZ3uHtBywj57?label=In%20the%20treatment%20of%20Sasha's%20teeth&amount=0.0037";
history.back();
</script>
Use JavaScript methods window.location.href and history.back.
Attribute target not supported
For HTML pages sources may be these:
<a href="http://Kristinita.ru/Donate-files/Bitcoin-Redirect" target="_blank"><img src="http://Kristinita.ru/Donate-files/Bitcoin-Donate-button.png"></a>
<script>
window.location.href = "bitcoin:1DF9jgzftTFn4ZnDV2YEjUtZ3uHtBywj57?label=In%20the%20treatment%20of%20Sasha's%20teeth&amount=0.0037";
close();
</script>
But GitHub as of September 2016 not supported target. See page source in Firebug, not target attribute in source.
