As I have lot's of images on page and small hosting space, I would like to host them somewhere else.
I've read that it can have negative aspect on SEO, but what if I make small high compressed thumbnail on site and large image galleries will load from external source? Will it be the same?
Also, as Picassa offers up to 16MP free image hosting, I would like to host my images there and link them with my site gallery. Is this a good practise? Is possible that links can be changed one day or am I violating their rules?
