My previous joomla intallation was hacked.

The hackers used the image upload feature to upload serveral files including a mail script and some html scripts for spamming and phishing purposes.

Now I have recreated my site (in joomla 2.5.4) from scratch.

However I would like to be certain this "leak" cannot be exploited again. Any ideas?

Well if you have a fresh and latest installation of Joomla! then there should be no-known way you can exploit it. The problem most of the time comes when you are installing components and modules that are not well-written and sometimes not even up-to-date so hackers are able to find holes into your site.

My previous install was not updated to 1.6/1.7 other than that no weird components (jcomments, jce editor, etc).

Are you sure that by default (for 2.5.4) files cannot be injected into the image directory?

At this time my permissions are 755 for the images folder.

I guess it will not hurt to add that code
(# secure directory by disabling script execution
AddHandler cgi-script .php .pl .py .jsp .asp .htm .shtml .sh .cgi
Options -ExecCGI)

thanks:)

it may also be that you are allowing via the registered users/allowed uploads people to put these files on

Indeed, you may let users to link images from other server but not allow them to upload them on your server.
