It would be that easy, if only I didn't have 60+ chapters...
I thought I could easily combine all the files together, in one go. But the idiot who uploaded the comic was really bad at organizing the files.
So instead of something like this:
0102
Chapter 1, image 2
It's
02
image2
So when I compiled all the files in adobe.
I got
02
02
02
02
instead of
0107
0201
0202
