how do i insert 2 photos in one post

The way you are doing it will only allow one photo to be uploaded. If you want to post more than one you will have to use a host site like Flickr and first upload you images there , then you will be able to post the image location onto this site to bring it up live. You can then post several images . You need to use the forum code shown above this new topic/reply box and wrap the location in between the square bracket img close square bracket and sq bracket/img close sq brackt.

There are more detailed instructions in a separate thread called how to post a picture.
