Updating Pandemic - On the Brink to In the Lab

The existing module for Pandemic doesn’t have the expansion In the Lab and I’d like to do it.
I’m having a difficult time figuring out what the current board and card pixel sizes are, how do I find this information?

The module is a Zip file, that contains a folder called images.
If you rename the module to .zip (instead of .vmod), then you can use any .zip decompression software to expand the file and examine the original image files. Then you can resize the new boards and cards to the size of the existing cards.
