Just a note, while the patch file is specifically for 4.1.10, there's no reason it shouldn't work on 4.1.9, just might require manual patching
While I do believe the {thumb} plugin itself is definitely better, keep in mind that Telafirma's mod has quite a bit of additional functionality added in. Dynamic Images has the potential to be better, but is pretty much bare-bones to start with. Just clarifying so you aren't mislead
Cheers!
