Here's how to post pics in your posts.
I've found the easiest way is upload them to PhotoBucket.com. The nice thing about Photopucket is it puts the image code in for you. Upload the pic then you can just click on IMG Code and it copies the link with the code to place them in your posts. Then just paste using CTRL + V or right click and select paste.
this is what the album pic looks like, you can place the cursor over any pic and the link menu opens to allow you to select the image links.



If you have any questions about other photo hosting sites like Flikr, post them up and I'll help you out
