Most of the comics I post from, such as Wawawiwa, XKCD, and Swords Comic, are simple copy/pastes. However, other comics like Our Super Adventure, Pixie & Brutus, and Me, The Family Pet? have to be built, panel by panel, to form one comic. This is either because artists have long comics that otherwise couldn't fit into one big PDF, or they separate the panels as a stylistic choice.
The GIF in this post showcases [most of] the process of me making today's thread of Me, The Family Pet? comics. If Imgflip wasn't so scummy with the limits of their free GIF maker, I'd be able to show the whole process.
So the way I make these kind of posts posts is that I copy/paste the first panel and count how many panels there are in the comic. Then I add however much space I need to fit all of the panels together. 4-panel comics are easy; It's just "space 100%, copy/paste, space 100%". Sometimes a comic has six panels, which would be "space 100%, copy/paste, space 100%, copy/paste, space 50%". Other times it's eight panels, ten panels, or an odd number of panels, requiring me to be precise with the spacing. Then I copy/paste the rest of the panels as images, resize them to fit the post, and stack them all in the order of the comic.
In places like Bluesky and Reddit's r/Comics, the individual panels are already there to be clicked on. In places like Instagram and Webtoons, you can't copy a PDF there, unless you resize your screen with your laptop's touchpad and use 'Magnify Image'*, which is how I'm able to bypass the barriers. Some Webtoons comics, like Cat Bird Dog, have PDFs that are misaligned with the panels, usually because the panels vary in size or are too big to fit into one PDF. And because CBD is a Webtoons Original, each episode is too long to make into one post, and I have to divide them into five parts. With those kind of scenarios, I just space 100% a couple times, add either all of the PDFs or however many I need, and crop out the stuff unrelated to the comic (usually merch adverts or image intros) and/or extra panels that bleed into the first and last PDFs.
*IDK if everyone can do this on their laptops.
It's a very long process that can take me about half an hour to do. But I do it because you guys love these comics as much as I do! And I'd do anything to showcase the art and talent that these artists are willing to put into their work and share with the world!
