when i wanna use iphone as hotspot, it only allow me to connect another phone through bluetooth to iphone or connect another pc through usb cable to iphone as hotspot, i cant use wireless as hotspot in iphone, is this normal?
No, I don't think that's normal. I use my phone as a WiFi hotspot all of the time, without cables or bluetooth. Maybe get it checked?

btw, how do i send picture out from iphone? it seems i attached my picture using email, but the picture is corrupted it happened many times. any ideas how to fix it?
thanks, first time iphone user here.

Sending pictures/files in iOS is a pain, I'll be the very first to admit that. Firstly, make sure you checked that your image is in the normal format (JPEG, PNG) and not in Apple's new
HEIC format which was introduced in iOS 11. What I normally do is I go to the gallery, select the photo/photos I want to email, select share and then send via email. Usually it works.
