problem with IImage browser

Hello, I just installed the image browser plugin

now when I go to the write page and press the image browser button I get the following message:

Warning: opendir(): open_basedir restriction in effect. File(/) is not within the allowed path(s): (/home/:/usr/lib/php:/usr/local/lib/php:/tmp) in /wp-admin/iimage-browser.php on line 540

Warning: opendir(/): failed to open dir: Operation not permitted in /wp-admin/iimage-browser.php on line 540

Cannot open upload directory 🙁
Check Destination directory and URI of this directory in admin area > options > miscellaneous

[root] />
Sorry, I can’t find any files in this directory 🙁

Close window

Does anybody have a solution? Thanks in advance!!
