Software that I use and rate as 5 star – some of it you buy, some of it is free – all of it is really useful (well to me at any rate!)

Artisteer – graphical web design software, especially good for Wordpress, Joomla, Drupal

Coffeecup – various options HTML editing, form design etc.

Photoshop CS3

Filezilla – free FTP transfer software

Roboform – free trial, fantastic for all those passwords!
