Yes, with User JavaScript. For example, see:
http://userjs.org/scripts/site/enhancements/block-external
Please read the notes prior to installation. Also, you should probably
edit the script prior to using it globally for all sites. Otherwise,
simply enable it for certain sites via right-click on page, "Edit site
preferences...", Scripting tab, User JavaScript files folder setting.

I'm not sure that it really is. The user Javascripts I've seen (including
the one you linked to) simply go through the document once it's loaded and
then remove the images. By then Opera has already requested the images
from the server and may have even got as far as displaying them for a
second before the 'onload' fires and the user javascript runs, so the
images haven't really been blocked, just hidden, and the remote site has
successfully served you their images and logged you. This will include
images inserted via Javascript which include a query string to gather
stats on browser, OS, screen size, etc. And that's before you start
worrying about things like javascript that fetches new images after the
page has loaded when you hover over things (either AJAX content or old
fashioned image swaps).
A genuine blocker needs to work at the same level as Opera's content
blocking, not at Javascript level. It has to decide to ignore things while
it's still parsing the markup and working out what further resources need
to be downloaded, and then continue working if the content of the page
changes dynamically after that.
Fundamental options like 'block all third party images' (at both global
and site preferences level) should have been part of Opera's content
blocking from the start. I hope they get added one day, but we've seen M2
spend a lot of time gathering dust since its initial release five years
ago so I'm not going to assume Opera will add seemingly obvious features
to the content blocking any time soon either, especially when they're busy
establishing 'partnerships' with companies and content providers who rely

This isn't what I want.

This would be handy.
