When you start a new thread/post, look down at the bottom where you clicked to post reply. Click on upload a file before you do 'post' and then it will show the directory files of your computer, and you navigate to it, and when you cli9ck on that file, it will be uploaded into your post if it is the correct format such as .jpg .jpeg .png .psd .gif Jim
Copying and pasting is also an option. That's what I do and it works out just fine. If you can, make the images a full image instead of a thumbnail.
