can't display uploaded images

hi everyone,
i’ve chaneged my wordpress to multisite and created another site, whole structure is ok, theme is running but i’ve got problem with displaying uploaded images, i’ve realized that i can upload them (server’s checked) but can’t display.
when i link images from the folder of basic site (the one before multisite) or eny other site like picasaweb it’s ok, it’s displayed, but not from the proper folder that belong to the site.

now it’s uploaded to:
wp-content/blogs.dir/2/files
before multisite it use to be:
wp-content/uploads
