Take a peek at section 2.6.6 in the Condor Manual --

http://www.cs.wisc.edu/condor/manual/v7.0/2_6Managing_Job.html#SECTION00366000000000000000

From the manual, it says:
Event Name: Image size of job updated
Event Description: This is informational. It is referring to the memory 
that the job is using while running.

So what is going on is Condor monitors the image size (memory usage of 
the job), and whenever the submit machine receives an update that the 
memory usage of the job changed, by default you'll get an information 
event in the job log telling you what the new size is.

Sure.  See above.  :)

On the "condor-page" ?  For better or worse, the bulk of the 
documentation on the Condor software is in the Condor Manual.  It is 
available in print (PDF, Postscript) formats, and it is also online as 
HTML --
   http://www.cs.wisc.edu/condor/manual
The Manual has a reasonably decent index, and in the online version of 
the manual, the index is hyperlinked.

Personally, I also have a copy of the Condor Manual on my Palm Treo 
phone in Plucker format - rather geeky I know, but I'd be happy to share 
it with anyone.

Of course, like most projects, the documentation has room for 
improvement.  We are trying - contributions welcome.  :)

Hope the above helps,
Todd
