How to remove other memory in Iphone?

I got large space of memory taken by "other", which is shown in itunes. I checked my usage in my iphone and i found that 5.2GB of memory were used up by photos. I try to delete it but failed.

i tried to restore my iphone and backed up, but it seems the "other" does go away.

Note: Iphone 4s IOS 6.1 Please forgive my poor english.

Make a backup on iTunes first and then do a system restore.

AT FIRST EVERYTHING WILL BE GONE but once the backup restores to the device, everything will be back to the way it was but without the "other."

The other is corrupted or fragmented files (Such as when you are transferring something from your computer to the device and then unplug it before it is done).

This was the best I could find for you.

If that doesn't work I'd say try to restore your phone in general, it may help.

NOTE: Your English is not bad at all, so don't worry about it! I understood everything clearly that you were asking and saying!
