From Wim Mostrey: Wysiwyg, CKEditor, and Wysiwyg Filter to allow customizations:
"A popular method is using the Wysiwyg module in combination with CKEditor. Enable the module, install the editor library and make sure to allow the img tag in your input format... install the Wysiwyg Filter module which enables a whole range of extra settings for input formats, allowing you to select which attributes, classes and properties should be allowed for which html tags"
