Inserting Different Images (Charts) in 111 reports and emailing using mail merge

Dear Colleagues,

I have to generate 111 individual reports and email individual reports to each student. The reports have two charts that I need to insert (as of now, I have all these charts in a folder) in the individual reports and email the report to each student. I am keen to use the mail merge functionality. How can I insert charts while preparing customized reports and email them to each student?
