Yesterday I wrote up a little howto for using html to align images - love that little hack by @awesomerobot and my colleagues will be excited about it. However I noticed that in my code example the image urls got changed from placekitten.com to the local upload. Not a big deal in this case and I realize this is probably impossible to prevent but it seems unfortunate that a code example can be messed up like this automatically by discourse.
The only way to stop it I guess would be to disable the copy to local feature, which I definitely do not want to do.
