Collect all images (.png) into a single HTML document

Create a PDF from your web browser as usual.

Example:

  python images2pdf.py  ~/my_plot_folder

that creates "~/my_plot_folder/index.html" and opens your web browser.
Most web browsers can "export" or "print" to PDF for sharing with colleagues.
