I see that Mycotopia forums reject an attached picture that it thinks is too large in points (pixels, on screen based medium). I understand that this must stem from the fact that the forum doesn't scale the picture to the browser windows or screen, making the zoomed in thumbnails, full size photos, appear inconveniently large on some screens.
What's the maximum size of an uploaded picture here? I'm not asking to make my pictures as large as possible, but to know if I need to resize some if they extend a certain dimension. I didn't see this mentioned in the guide, sorry if I missed it.
I guess if we want to be polite to other users the pictures shouldn't extend 1280p width, for compatibility with displays of previous generations.
