Forum:Can't upload large promo images

I tried to upload the full PNG denoised version of this image(Chrom_Marth_dueling_artwork.png), but the wikia wouldn't let me because it was larger than the allocated size; it was 15 MB, even PNG crushed with Optifine. Is there some way for me to put the full image on the wikia? Robotortoise (talk) 04:25, May 13, 2016 (UTC)
