Images & Videos (uploading, searching, attaching)

Images & Videos (uploading, searching, attaching)

Hi, I am not a developer so please excuse the stupid question. My friend's Kaisa's best friend is in the middle of creating a very content heavy community site that has all kinds of life-style related information (finance, health, travel, how to life a good life style etc).
He was told he should use DRUPAL for this site which I assume will be very popular as it will also have some ecommerce features, membership, possibly events, bloqs, newsletters.
In addition to trying to decide what are the features he really MUST have and what he can add later to be smart and keep the site userfriendly my friend asked me a specific question about images.

She is a not a techy either so she explained this in 3 parts:
1. Drupal probably allows uploading/attaching images for member profiles what ever those are.
Can that feature be customized to allow certain sizes (several of them), captions on the pics and allow printing those out/send them out as eCards
2. could one possibly set up a search function next to some "idiom", "quotation" etc where the drupal site would search an approriate image (possibly paid image) from certain sources or any sources.
3. Could one set up a media library type of image storage/video storage where the users could freely select certain size of pictures, posters etc for different purposes whether it is sending eCards, posters, emails..

I assume there is a way of linking to youtube, googlevideos...at least if you know a link but maybe even if you just know a topic/interest?? Automated search that is...
For instance for the Formula 1 person...

He is interested in Formula 1, maybe likes to send emails for "events", "newsletters", private messages to his "mailing list"....or even use those images for his ecards, profiles, etc
For example: "I love Formula 1 races."

Thanks,

email also for me erikaeder(at)hotmail.com
