When I had less than 50 posts, I could just use the gallery and link images to my posts.
1. Do you see "Image Gallery"? click it. and then create your own gallery.
2. Create your album and make it private if you want to..
3. upload pictures.
4. after uploading pictures, click on pictures for bigger size
5. right click on it and select "Copy image location" if you use firefox. If you use M$ then select "Properties". when Property window shows, you can see the URL of image. Copy it.
6 Come back to forum and click on Reply or New thread.
7. <-- Click on this image and paste the URL you copied.
8. Preview your post.
