We all used to use a free photo posting site called PHOTOBUCKET...
I had probably over a 1000 photos on this site to post on the various forums and all...
Then the company wanted to start charging for their service and held all of our photos for ransom. I got most of mine back eventually but did lose a few of them.... Lesson learned here was to always backup important to you items on special hard drive hehe...
I now use IMGUR to do the same thing and it has always been free to use as well...
Using the posting service is almost CLICK CLICK to add to the forums and all... Their sites have the proper HTTPS addresses assigned to your photos you need to post the photos
