Using your robots.txt file to block googlebot-image from discovering your image files:

Make sure you block only the image directories that you do not want indexed.

Also, if you do not use Google’s Webmaster Tools, you may want to investigate. This service offers many tools, including a list of which files are throwing 404s. http://www.google.com/webmasters/tour/tour1.html

Do you mean while I get this situation worked out? Or do you mean that people are working on this because numerous people have been getting this issue?

I’m not sure that the word numerous applies as I’ve only seen a half dozen or fewer threads with this particular issue. Remember, one person’s 404 is not necessarily the same as the next persons.

This type of issue often comes down to one or more factors: bad install, using too old a version of WPMU or BP, plugin conflict, custom theme issue, apache issue, ISP limitations.

We can try helping you with most of these but do not have any control outside the core of the BuddyPress code. We investigate as best we can with the information provided and if it is caused by BuddyPress, offer a fix in trunk.

I see in another thread that you are on Slicehost. I’m with them as well. Since you have to set up your own slice, there may be an apache issue. So, to better understand you particular issue, please provide some more details:

1. Have you tried deactivating all non-buddypress plugins, wp-super-cache in particular?
2. Have you tried using the default .htaccess file that ships with WPMU?
3. Are there any PHP errors in your log files?
4. what are the other listed errors in your apache log?
