    ``pdfTeX warning: pdflatex.exe (file
    ./8073c8x-eps-converted-to.pdf): PDF inclusion: found PDF version
    <1.7>, but at most version <1.5> allowed

Those are warnings, not errors. Are you sure the graphics are not
getting included despite those messages?

It is possible (though unlikely) that the graphics actually require PDF 1.7.
You could add
  \pdfminorversion=7
near the beginning of your document. It should eliminate the messages, anyway.

    LaTeX Warning: Float too large for page by 501.51253pt on input line 10''.

Another warning. Maybe something needs to get scaled down.

Hope this helps,,
