Step 2: This step will vary depending on where you want to upload the image to.
Forum posting you need the [IMG] [/IMG] codes
Homepage/Product Page you need the HTML code
For just posting the link for an image to large you will need the "direct link" code this code will start with something similar to www . whatever. com the fastest way to get the direct link is to copy what is in the address bar at the top of your page.
Step 3: After copying the proper code for where you are posting the image just go into either a blank forum post or the proper place in your hp and paste the code, after you do so either post or save and your image should be on your post.....I hope I didn't confuse anyone!
