Let's say I want to upload to two places in particular: Webtoons and Tapas.
Webtoons has a 800px x 1280px page size with a maximum file size of 2MB per page, with a 20MB maximum episode limit.
Tapas has a 940px x 4000px page size, with a maximum file size of 2MB, with 40 page limit.
Now I could very well plan within the limits, resize each one by width, and use a page cutter to dynamically cut the pages.
Sure that would work.
But what if I as a creator didn't want my panels cut across, what if I wanted control over where is cut is?
Do you not see the problem with have a 40 page limit?
