When you click the Reply button and the page opens up where you type in your text for the message, look under the text box where it says "Click here to upload images and files!". Once you click that, a new small window pops up with a bunch of browse buttons. Click the first one and then using the interface, browse to what folder the picture islocated in and double click the picture file or once click then click Open. You can repeat that process several times(once per each browse button). Once you are finished there, click the OK button at the bottom of that browse list window and the files will be uploaded. The, it will tell you finished successfully and you click OK. The you can either add more text here in the text window or simply click the OK button under here when done.
