How can I make sure a 'partial' get put in the rw_common subdir?

I have a banner image that I made into a partial and use at the top of every page. When I export the project this image gets copied into every index_files subdir which causes it to be reloaded each time a new page is visited. Is the some way to make RW put the image in the rw_common subdir so that it gets cached after the first page load?

Thank you for any help you can offer!


You need to warehouse that image and then it gets loaded once and then cached. Foundation does this really well.

Outstanding! That works really well. Thank you for your help, webdeer!
