Search and replace nightmare

I’ve just done a url transfer and am trying to do a search and replace with this plug in - http://wordpress.org/plugins/search-and-replace/installation/

However there seems to be a strange string in the currunt image like so:

/home/sites/salafiwales.co.uk/public_html/wp-content/uploads/et_temp/what_we_offer-48944_232x117.jpg

How do I do a search and replace. The plug in is asking for the following fields:

Search for:
Replaced with:

Really hope you can help
Many thanks

ok I’m going to do

search for: /home/sites/salafiwales.co.uk/public_html/wp-content/uploads/et_temp/
replace with: public_html/wp-content/uploads/et_temp/

My question is do i include the public_html/ in the srting or omit it and do I include forward slash at all?

some help would be greatly appreciated
many thanks

This can be be solved in an easier way and without plugin, using the search and repleace script by interconnect. Script and detailed explanation can be found on the following page - http://interconnectit.com/products/search-and-replace-for-wordpress-databases/
