Remove member search, show images on HP with latest posts

Hi –

I am working on an install of buddypress social – two things:

1 – I don’t want a member search to be the first option everywhere – I only want this to be an option in the members area – how do I remove this entire search form from everywhere but the members area/Template

2 – I would like images to show up with their posts at all times, but especially when extracted onto the home page for ‘show latest posts’ widget and for the category subpages – is this possible?

3 – the image that i have uploaded for the gallery, which I’ve uploaded into the media area, is not showing – as it does on the example of buddy social. Where do I set this!
