Resolved Best hosting method for labeled images?

Not a great thread title, I know, but I couldn't think of anything better :-.

My question is this:
I want to upload some small, named jpg images (say, under 1mb each) to a website where they can be found by a Google or similar search for a certain name.

For example, if I upload a jpg named Horatio Hornblower.jpg, I'll want it to be located by someone doing a Google image search for 'horatio hornblower'.

So - is the best method to use a photo sharing site like Photobucket or Flickr etc? Or would it better to use a blog site?

I don't want to pay for this, so any method needs to be free.

I ask the question because I'm not sure that Google image searches return data found on say, Flickr, Photobucket, SmugMug etc.

Thanks
