New feature to make it even easier to post images! 
To post a photo from your gallery, visit the page with the photo, and underneath it, you will see a box like this:
Place your cursor in this box, right click and select "copy"
now you have the code perfectly formatted to post in your thread
Just visit the posting page where you want to post your message,
place your cursor in the wysiwyg (what you see is what you get) editor (the window where you type your message), and either click Edit -> paste
or hold the Ctrl key while mashing the letter V (Ctrl+V) to paste your image code.
Now click the preview button.
You should see your image appear in the preview. Now, if you are happy, click to post your message, or click to keep editing and previewing before you post everything the way you like it.
