Stug, once you click the go advance button at the bottom right corner your new screen comes up. You must then scroll down this page until you see the Manage Attachments button, this gave me fits when I first became a member here because I couldn't find the MA button. I didn't know where it was located and just by chance stumbled upon it.Once you click this button you get a new smaller screen. Towards the upper right corner you will see the Add Files button, click this. You have a new window within the one you just opened, click the Select Files and this should take you to your computer documents and photos. You can now search your photo. Once found, click the photo, after you have downsized it, and then click the Open button at the bottom of the list. This loads the photo into the small Attachments window. Once there click the Upload files button and your photo should show up at the bottom of the Attachments page. You can now click the Post reply button and you should be done. Hope I haven't confused you to much.
