Probably the easiest way would be to sign up with a free web photo hosting site like
Photobucket.com (that's what I use). Follow their instructions to upload your image. Once you have your image on the web, you just need to paste the URL address into your post here. (It will be something like
http://photonamehere.jpg)
If you use Photobucket, under your image you will see a series of four URL addresses for the image. The fourth one down will say IMG Code. Copy that address, and you can paste it directly into your post. Alternatively, you can click on the "insert image" box above where you type your post here. It's the one that looks like this;
.
In either case, all you really need is to type ["img"] before your picture URL and ["/img"] after the URL. (Leave out the " before and after "img", but I had to type them so that the computer wouldn't see my typing as an image.) That's what clicking on the
box does for you.
I believe that you can put something like nine images in one post. I like to center my pictures using the
button, and to put a space between them by hitting "enter" on your keyboard. Of course, that's just a personal preference.
