Cannot put images

How can I put images! I already download the images and put them on a new carpet named “img” and I put the name of this image, but it does not appear!

Good day!

If you’re referring to linking images via href tag, path names are case-sensitive; img333.jpg is different than img333.JPG

Please recheck your path name.
