Reproduction Permissions and Copyright

A small periodical that we subscribe to regularly, publishes a series of tables or graphs with general economic data content. Each of the tables and graphs clearly footnote the open source name of where the data was extracted to generate the table or graph.

We'd like to incorporate some of these same data sources into a revolving economic "dashboard" on a website we're creating for the employees of our company. We could easily recreate these same tables or graphs ourselves, using the same source locations, and cite them as the periodical does, but because of time and quality of the original tables/graphs, we'd like to just scan the graphics as some type of graphic file - and use it directly. We're happy to include the original source footnotes and willing to provide attribution back to the periodical.

Is this a permissions or copyright infringement issue? The funny thing is that our website is an intranet system, which is completely separated from any external links, so only internal personnel would have access to and see the graphics on the dashboard. Regardless, we'd prefer to be legally compliant with existing copyright law.

We're also in the process of requesting reproduction permission from the periodical directly.
