I have been using Photobucket for years. I even paid for a premium account so I could post movies. This year Photobucket started putting advertising on their site and that really slowed things down, so I paid to remove the ads. In spite of that Photobucket has gone down once in a while, which is even more annoying since I am paying for it. At the very least the pages can be slow to load, so finding a particular picture can take some time. To beat that problem I have a spreadsheet with links for many, but not all, of my pictures, so I often do not have to go to the Photobucket site to grab a picture.
I have written this article on how to post pictures using Photobucket:

Flickr does not have a link with just the IMG code, the IMG code is buried in a very long group of characters. I have to copy and paste the whole works, then erase the stuff that I don't need. Flickr pictures are included in my spreadsheet and the links only include the IMG codes.
I do delete pictures from both accounts from time to time. I try to avoid deleting pictures that have been linked to slot BBs. Most of the deleted pictures have been ones of old race results or possibly diagrams that have been replaced with better ones. If you ever run across one of my posts and the picture is missing you can always shoot me a PM with a link to the post and I can send you the picture if you want to see it.
