wp2static & photo-gallery extension

Hello,
A website I host is using the photo-gallery extension :
https://wordpress.org/plugins/photo-gallery/
Unfortunately, this extension is not working with wp2static.

After inspecting the source code I think it is because the gallery’s picture are loaded with JS.
But their URL are in the static source code, just buried in a JSON string, in a very long autogenerated line.
Is there a way for wp2static to scrap these url ? It may be enough for the photo-gallery extension to work in static mode!

I don’t know how much work it may take, I’m just asking if this is feasible.

Thanks for your work !
