I have this image on my files but when I upload it to studio
the image won’t work or won’t appear. Are there any solutions?
Upload it as a decal to Roblox first.
then i would recommend you to Upload it via the Roblox Create Page like @LandnBlu already said if you want to Uplaod it via the Roblox Create Page click on the section Decals and chose your image then you can Click Upload.
