lolly, welcome to the forum. The easiest way to post pictures here is to open an Imgur account, load the pictures there, and then paste the BB link into your post here.
It’s the same idea as set out in this thread

Don’t use Photobucket, though, unless you want to pay a small fortune for the pleasure.
Alternatively, make sure the file size of the photo is less than 250KB and use the attachments feature of the forum.
Yet another alternative if you’re using a smart phone to take pictures is to install Tapatalk and use it to load photos. It does the same thing as Imgur but hosts the photos for you.
