Hi,
I've searched my FTP for the TimThumb within CORONA, but I haven't found any file concerning this.
Then I used this plugin
http://wordpress.org/extend/plugins/timthumb-vulnerability-scanner/
to check, whether I have an unsafe TimThumb at my Wordpress - and the plugin found a lot of TimThumb-files of other themes, that I have installed, but nothing within the CORONA theme.
Where is the TimThumb script for CORONA and is it a new, safe version? Where can I check this?
Thanks.
Create a new thread and tell me what problems you are encountering and what you want to know. 
There is no step 3 :)
