If you'd like to post pictures, the best way to do it is create a photobucket account, upload your pictures to it, then use an image tag to show them.
Doing it this way will save storage space on the forum and you should be able to keep the picture resolution higher.
Photobucket accounts are free and uploading is easy.
Once you have a picture you want to show, simply copy the IMG code, which is directly below the picture (in most browsers you can simply click it and it will say "copied"), then paste the IMG code into your post here.
This image shows my photobucket account.
First click the little gear by the photo you want to display. Then click "get links".

Now click in the IMG box and the link will be copied. Then paste that link into your post (control+V or right click and paste).

If you already have clicked on an image - the IMG code option is to the lower right as show here. Just click in there, it will say "copied", then paste it into your post.

Here is a short video showing how to add photos:
You can see notes / pointers in the bottom left, but they are a bit hard to read on youtube.
If you use the [ ] button in the lower right of the video it goes full screen which helps with reading the text.
