If you want to use the embedded vTiger install on Elastix or on any asterisk distro as the sole interface for your clients' normal usage and wish to place your logos and remove the vTiger and vtigerCRM words from all but the footer, the following notes will be useful. The version looked into is
v5.0.3 but should be a general guide to other versions.

A replacement for the webmail_header.gif is here:
The honestCRM.gif can be replaced by a copy of topBg.gif from the same folder while the honestCRMTop.gif can be replaced by a single transparent pixel blank.gif file - all files being renamed as the original filenames they replace.
