Need help with cover scans.

I'm working on a discography of the bands official work
and was looking for the following pictures (about 500x500
pixels would be great)...

I need:

The cover to Melon
The cover to Put Em Under Pressure single (Larry!)
The cover to Heroine single (Sinead and the Edge!)
The cover to Two Hearts Beat as One (have a small one, need a larger
one!)
The cover to "40" single (Netherlands only release)

Please do not send them to my posting address...send them to
****@is2.dal.ca instead. Any help would be greatly appreciated.
Thank you.

Aaron
