I opened the maps up with Gimp and exported them as webp, which drastically cuts down their file size.

My question is, can I easily swap out these two files in the images folder and FG will just place them as the background in relation to the items and walls that I have already placed? Or will I need to start over because FG pays attention to the file extension. I think the answer is the latter, but just wanted to make sure.
If the filenames are exactly the same then you could replace the new one with the old in the images folder inside your campaign. (The exact same means also the same file extension as well - so .jpg isn't the same as .webp even if the name is the same). However if you export the map that you currently have using the small export icon at the bottom of the map panel you'll get an xml file with the same name as the map. Replace your existing image your new one (keeping the name the same) and then re-import your new image into your campaign (make sure that the xml file is in the same folder that the image is in before you import it). The xml file will tag along and your occluders will remain. Note that whatever layers you added within FG won't be preserved (apart from the wall occluder layer of course) since you'll be replacing the original image only.
