So I decided to customize the home page of a wiki every month, and so I need to change certain images.
I wanna use images that are already available, but some of them just aren't the same size as the rest of the images in the gallery, and I can't just add widths=200px to the gallery because it doesn't work. Is there any way I can resize only that one image? I will mention that the widths tag doesn't always change the size of the image (no matter the number I pick, the aforementioned 200px doesn't change anything at all) and I prefer not to upload a new image every month just for the home page.
