Your webserver logs (if properly configured) will give you all the information you need (al the warnings about fake-referer headers still apply of course). With some scripting you'll even find the grandparent-referers if thats what you are after.

For instance if you look at this apache access log (I've modified the content, so might contain typo's): 

1.1.1.1 - - [10/Jun/2004:14:50:41 -0700] "GET /index.html HTTP/1.1" 20
+0 808 "http://www.othersite.com/" "Mozilla/4.0 (compatible; MSIE 6.0;
+ Windows NT 5.1; FunWebProducts)"
1.1.1.1 - - [10/Jun/2004:14:50:51 -0700] "GET /index2.html HTTP/1.1" 2
+00 1200 "http://www.mysite.com/index.html" "Mozilla/4.0 (compatible; 
+MSIE 6.0; Windows NT 5.1; FunWebProducts)"
1.1.1.1 - - [10/Jun/2004:14:50:51 -0700] "GET /logo.png HTTP/1.1" 200 
+15000 "http://www.mysite.com/index2.html" "Mozilla/4.0 (compatible; M
+SIE 6.0; Windows NT 5.1; FunWebProducts)"

You can see somebody came from www.othersite.com to www.mysite.com/index.html and after 10 seconds he loaded index2.html which contains logo.png. If you can't get this information from the logging provided I suggest you read the Apache documentation on their logging formats.

Why do you need a picture-referer-thingie for that?
