I'm using the free Google Photo storage application with great success and highly recommend it. Especially so if you are already using Gmail or have another Google account. Within your Google Photo account, you can have as many "albums" as you wish and can set display permissions for each album independently.
For one thing, Google Photo seems to give you more storage space than any other ap. It also seems like with Photo Bucket and some others, that display times "time out" and your photos disappear from your postings. Not so with Google Photo.
Google also offers you Picassa, their photo utility, which streamlines uploads and allows you to modify display.
To post a photo, all you do is display your photo within Google Photo, then right click to copy the URL for that photo. Then you go back to your [Hobby-Machinist] post, and paste the URL into the Image URL query. Or you can post a link to the entire album, which is very handy when you have something for sale. I'm no computer guru, yet find it straightforward and easy.
