I thought this was quite well known to use as a defensive trick to stop cannon rush. Sunken next to hatch but out of cannon range has extra reach to defend hatchery, i thought it was deliberate rather than a bug prehaps because of the annoyance/power of cannon rushes (including fastest/other game maps) in early Bnet.
If you're on other browsers, you can use the bookmarklet I made using the code in the above extension. To make this work, create a New bookmark, add a title (e.g "Fix broken images"), then in the URL field paste the code behind this link. I made a back up for the code over here.
To use this, go to the page with broken images, then left click the bookmark in the bookmarks bar. I tested this bookmarklet on Chrome and on Firefox so far, but it should work with others as well.
Thanks to yldzhanhandan for making this extension and also thanks to you, StRyKeR, for making this thread!
