Hi!
1- How can I show 'Processing' message on desired place. Currently it is showing on column names.
2- Can I change 'Processing' message with some image ?
The styling (and to some extent the positioning) of the processing display element is done via CSS. Please do indeed customise this as much as you want! - http://datatables.net/styling/ids_classes . Also you can change the language text using oLanguage.sProcessing: http://datatables.net/usage/i18n#oLanguage.sProcessing , which will take HTML as well if you want to put something complex in there rather than just a string.
