Image not uploading!

Hello,
if you can post the form code also, so
1) you have to add <form enctype="multipart/form-data" , the entype on form open tag
2)ideally try to use the example from CI toturial input
3) print the upload error so you can see whats going on
4) dont forget that you have max size 10mb but the server maybe is on 2mb , so you have to check the server too!

Thas all
