thumbnails not showing

[Katrina18]

i don't know why, but everytime i upload a picture now it shows the picture, but it doesn't show the thumbnail. does anyone know what i did or what might be the problem?

you don't see the thumbnail ? where in the right after the uploading? it's natural

if you thumbs are not created at all, you do not have GD support installed in PHP. ask your host admin to do so.
