Halloween is our favorite holiday around here, so once again we put together a new batch of Halloween wallpapers for 2026.

This year's collection includes 20 widescreen images, ranging from classic horror to some very MajorGeeks-style weirdness. We have Frankenstein coming to life, a vampire crawling out of his crypt, witches in foggy graveyards, a werewolf practically on top of the camera, aliens conducting an examination, Bigfoot proving he is still the world's undefeated hide-and-seek champion, and a group of cryptids sitting down for a poker game.

A few are more playful. Trick or Treat has monster kids out collecting candy. MajorGeeks Raid Party turns classic PC gaming into a fantasy dungeon crawl. BSOD takes the Blue Screen of Death rather literally, while Skeletons in the Closet takes another familiar phrase and turns it into an actual scene.

We also played around with some more conceptual images this year. The Devil Is in the Details hides something sinister inside a wall of data, code and charts. Another image imagines AI itself as something quietly watching from inside a massive data center. Some are obvious Halloween monsters. Others are the sort of images where you may notice something different the second time you look.

There are also a couple of reimagined classics. Norman Scarewell takes American Gothic in a more monstrous direction, while the Thanksgiving dinner scene brings a whole collection of familiar monsters together around the table like one big dysfunctional family.

All of them were created as large widescreen images intended to work well as desktop wallpapers, including modern 4K displays.


We included a theme pack file in the zip for Windows users. Just double click it and it will apply a dark theme to you PC and rotate each background at 30 second intervals

You can change the wallpaper timing, shuffle settings, or switch themes anytime under:

Settings > Personalization > Themes
or
Settings > Personalization > Background

So How Did AI Do This Year?

This is actually the third year we've done this, and the wallpapers have become something of an annual state-of-the-tech test for us.
This isn't really meant to settle the argument over whether AI-generated images are art. That debate can go on forever. For us, this is more about seeing how the technology changes from one Halloween to the next. And the difference between 2024 and 2026 is pretty dramatic.

Back in 2024, making some of these images was much harder than you would expect. Getting the correct aspect ratio was nearly impossible. Asking for a specific composition could send the image off in a completely different direction. Small changes often meant starting over from scratch with hallucinations becoming not just persistent, but imbedded. We also have far less 8 fingers on one hand results...but not zero.

The guardrails were also extremely restrictive. Pretty ordinary Halloween ideas could unexpectedly get blocked simply because the prompt included things like monsters attacking, vampires rising from coffins, or other basic horror-movie imagery. We spent a surprising amount of time rewriting perfectly harmless Halloween prompts just to get the generator to understand what we were trying to make.

That has improved considerably.

In 2026, the biggest difference is how much easier it is to work with an image once you have something close. We could generate a scene and then say, "Make the werewolf more realistic," "Remove the extra dog," "The vampire's hand is on the wrong side," "Those characters all have the same pose," or "Make the hidden face less obvious." That kind of iterative editing is much better than it was even a year ago.

Speed is another big improvement. Earlier generations could take long enough that a failed render or timeout really killed the momentum. We were alos quite often banned for using too many recourses. This year we could try an idea, reject it, make a change and move on without spending half the night waiting for the image generator.

None of this means the technology suddenly gets everything right. We still saw extra fingers, odd anatomy, repeated poses, strange perspective choices and the occasional image where the AI clearly misunderstood what we were asking for. Some ideas took several attempts before they looked right.

But that's actually part of why we keep doing this every year.

The interesting part isn't just that the images look better. It's that the process has changed. In 2024 we spent a lot of time trying to make the AI cooperate and using external tools to make them usable. In 2026 we spent much more time actually experimenting with the ideas.

That's a pretty big leap in only a couple of Halloweens.

We spilt this collection off on its own as the package was getting large. You can compare this year's collection with our previous versions here:
