mobile vs. desktop issues

one of the pages (The Purpose) on my site http://www.barnabashouseok.com shows a different pic – the correct one (preacher just to right of the title) on my iPad and laptop than it does on my iPhone – incorrect one (church to the right of the title). i’m in Oklahoma. my friend in Kentucky can find the preacher pic on his iPad or MacBook.

also, on my iPhone some of the tabs at the top of the page aren’t showing – The Plan, The Provision, The People, The Post. on the iPad, only The Post isn’t showing.
