Scenario: developing large suite of Crystal reports that will be installed at multiple sites.

Feature needed: insert logo into reports - each site having custom logo.

Solution:put only logo into a report - then from all other reports insert 'logo-report' as sub-report - select sub-report in design view of main report - Rightclick and Format Subreport - select Subreport Tab and check the Reimport Subreport on Load box.

Works great, underlays logo so you just allow clear space for it, and adjusts to logo size so can be horizontal or vertical as needed.
