I read and tried and that WORKS. just follow the steps whom cant do ftp upload.
1. create a category. and take the url address( just the number at the end)
2. than go to data/media/## (## is the number that is wirtten at the end of the url)
3. upload pics to that directory (##) via FTP
4. go to admin panel and check "Check new images "
5. it wont find ant pics
so ypu have to choose the category. then try again.
6. that's it!! prey for theram
7. dont forget to create the thumbs (after preying)
