first click the button to post a REPLY,
or type something at the bottom of the page in the "Quick Reply" box and hit "PREVIEW" (not post).
that gets you to the full post page, where you can ATTACH image files.
then just attach your image files using the browse button and then if you want to show the images in your post at specific locations put [attach] in your text to show where to show the image (if you dont they will be shown as thumbnails at bottom).
Ah, thanks. I was doing that, but preview didn't show the image... I'll try again, thanks...edit by jgpaiva: fixed quote tag
