ellou' David and List!

I was fighting with this for few hours and finally found the problem, if 
you're still with no thumbnails there's the reason - empty space after 
?> tag (end of php script) in some configuration file (in my case it was 
realurlconf.php and of course it was MY fault, as I wasn't clear)

In this situation thumbs.php just returned image data BUT prepended with 
two empty lines... it's easy to verify, first edit the file: 
typo3/thumbs.php and comment this line (it's at the end of main() method 
line ~248):

header('Content-type: image/'.$outext);

Next open directly the script necessarily with parameters generated by 
BE (md5 checksum!) for your example it's:


You'll raw image data, just open the code preview to check if it begins 
with empty line(s), if do... you have to search where it's placed... 
boring task, but it's working! now I've my thumbnails again! :D
