I host my photos on postimages.org and link to them in my posts using the img tool. Postimages has a mobile friendly and super easy interface for uploading photos and copying their links. And it’s free.
I know the potential con is if postimages ever decides to not be free or go under, my links will break. But on the upside, they’ve been around for a long time and hopefully won’t pull a photobucket on us...
The big pro for me is I am active on several forums (this one and some for my Jeep) so I can have a central place to store everything. I can link to the same photo in different forums.
