To post thumbnail pics off of your computer, use the 'manage attachments' button under the reply box to upload them onto the thread you're replying to... To post a pic from the internet somewhere, find the pic, right click on it, copy image location, then click this little box () at top of the reply box...a little box will pop up, and you paste the url into that box and click ok
1. Find the image you want on your computer. 2. Go to ImageShack® - Online Media Hosting and upload it 3. Copy the 'direct link' address 4. Or... If its an image on another website, right click the image and select 'Copy image location' and follow step 4
I'd get a photobucket account or something like it and upload your pix there. Then grab the direct link and click the image button and paste the url. The image button is the 5th from the right on the bottom row. I love inserting images in to my posts to really prove my points.
