Don't use Photobucket - they effectively held their free accounts to ransom several years ago and ask for payment should you wish to share your photos to other web sites via linking.
Flickr (as found on some other web sites) can show problems with linking - photos not being visible.
Many here now use
www.tm-img.com, set up by a member and administered by a couple of members.
Instructions for use here:
https://www.tm-img.com/page/ifu You'll need to create an account to see the instructions. It's fairly simple (if you are used to messing about with Flickr!).
It's free to TM members, paid for on a voluntary donation basis.
Don't attempt to upload photos directly into a thread - that was effectively disabled some time ago when the list owner / moderators were trying to resolve very slow loading forum.
