If you set it to allow permanently, there is no way for the user to turn the block on again without fiddling with code. Even if they set it to an hour or whatever, they may want to turn it on again early, which they also cannot do.

I was thinking maybe if it detects it was an nsfw image, it shows an extra button which lets you block nsfw images.

I talked about this on Reddit, and found a solution with some help.

I made the following (somewhat) easier solution that less technical people can use. It uses a bookmarklet.

Make a bookmark, call it what you want. Set its address to: javascript:url="http's://image-generation.perchance.org/embed"; if (location.href!==url) { alert("Opening to correct page. Run this again."); open(url); } else { localStorage.okayToShowNsfwUntil="0"; alert("NSFW setting reset."); }

(I would put a link you can drag into your bookmarks, but this forum doesn’t recognise “javascript:” addresses.)

Note that this will run JS code in your current page. though you can see what it’s doing if you’re worried about that and decide if you want to use it or not.

With the code formatted more clearly:

url="https://image-generation.perchance.org/embed";
if (location.href !== url) {
  alert("Opening correct page. Run this again.");
  open(url);
}
else {
  localStorage.okayToShowNsfwUntil="0";
  alert("NSFW setting reset.");
}

If you’re not in the right place it opens a window to image-generation. And if you are in the right place, it resets the okayToShowNsfwUntil flag for you.

I hope this helps people in the meantime. But it would be great if there was something built-in to image-generation so people don’t have to find this page and make the bookmarklet and all that.
