General Support: i can't see big pics only thumbnails

when i upload a picture then later i can see it with all the thumbnails but later when i try to see the very last big pic it doesn't show up.
here it works
http://www.francojony.com/ploggerb/index.php?level=picture&id=2

and when i click on it it doesn't work and i have this
http://www.francojony.com/ploggerb/images/my_collection/baby's/intelimac20060113.jpg

i also notice that those pictures are being written in chmod 600, well if i upload myself a puctures normally they are always chmod 644 as default so you can see it then if i change it my seft to chmod 600 then i can't see it so why is this happening any way in the plogger itselt. all my path are chmod 777 so what is happening.
i mean
all this path is chmod 777
/ploggerb/images/my_collection/baby's/ as you can see they are maps
but just the picture at the end of the path is chmod 600
/ploggerb/images/my_collection/baby's/intelimac20060113.jpg
