photos IN posts

You have to resize the photo first with resizing software like Windows live photo gallery or another photo editing software.

Then in the advanced reply screen here. There's a little paper clip looking
icon at the top of the text screen. Like this.
When you put your cursor over it it says attachments click it.
It drops down a menu to browse for the photo on your computer you want to post.

Once you have browsed and found the photo you want double click it and it will load to one of the blanks . After you have all your photos entered click the upload button at the lower right. it sometimes takes a bit of time to upload the photos. It depends on the what you resized them to and how many you are uploading.
Here's a thread that might help too.
