Primepress multi-site headers?

Greetings —

In searching around the WP and other forums, I see that others have similar problems, but I haven’t been able to locate a fix for this one:

I have three Primepress blogs:

#1: http://composing.org/composition2/
#2: http://composing.org/wrd104sq2011/
#3: http://composing.org/wrd103aq2011/

I really like this theme, and it’s wildly useful for teaching sites. #1 was first, last year. When I created #2, however, the header I used replaced the #1 header; and when I created #3 this year, that header replaced both #1 and #2, such that now all three sites display the same headers when, in fact, each site should have its own site-specifici header.

Make sense?

Is there a way I should be naming these images within the themes > primepress > headers directory? Or is there another strategy such that a new site will not override previous Primepress site headers?

I’d be grateful for any tips or advice.

Thank you!

Best,

Michael
