alright, i was finally able to get it all sorted out. i didnt automate it because it seemed a little intimidating downloading apps/scripts just to do covers for me. but at least i know i did it somewhat right. ( or as best i could)
since you said cbz. files work in 7-zip i simply extracted all magazine issues to a folder, deleted everything but all "0, 00,000,1,01,001" cover files and manually named them "Front - Gameinformer issue #_"
it was time consuming doing the naming thing, but it was super easy and fast to import them afterward.
i couldnt find out how to import them as a batch but i found out you can just drag and drop an image into the metadata editing page instead of having to click the add button and add it from the pop up window.
after that it was just a matter of continuosly just clicking next and drag and dropping the images.
it was a little time consuming and im sure there are faster ways, but i gotta say, now that its done i feel extremely satisfied.
