Buddypress Activity Plus

I am facing a problem with Buddypress Acitvity Plus. Whenever anyone tries to upload multiple images. All the images Comes stacked vertically (Every image comes below the another image in one column) I just want them to appear side by side. I am not a coder so please tell me everything step by step (what i have to write where and in which file.)Please Help me to fix it.

And my second problem is that there two up and down arrows are coming just next to the post button in activity stream (main page, profile and in groups)of buddypress please help me to fix that too.

I am using Road Fighter theme.

My site is = http://www.socialn.tk

Thanks in Advance.
