in 1.3.6, the comic easel import was made. This is meh, largely untested except on my dev machine, but if you have the need to add a bunch of comics at a time; this is what you would use right now.
The first release of the import uses the ComicPress naming convention for files, YYYY-MM-DD-title-of-comic.extension
You FTP into your site, create a directory off of the root of your WordPress installation and name it ‘import’ … FTP the comics you want to import into that directory. Create the chapter (or make sure it’s added) in the Comic -> Chapters section of the wp-admin and then.
Rinse repeat for set of comics, in each ‘chapter’ you want to add. If you only have a basic chapter made for all comics, don’t stress about it; you can still use that main chapter.
Like always, try not to overload your system’s processing by adding too many comics at once.. keep the importing at a min. I suggest 20-30 comics at a time max for good solid hosting and 5-10 comics max if your hosting isn’t really that great.
NOTE: It will actually add comics that are set on the same date, just currently not modify the time on it and there’s a big change the image won’t get attached.. known bug on that so I just currently say don’t do it.
