And what about my own files saved in my compute? How to upload them? And How to highlight (Where's the option)?
use any of the image hosting sites (calling Tofu for his repository of useful links)
Upload your images anomymously (don't need to sign in)
www.imageshack.us - upload your own image or transload (get a url from another website), you can resize on the fly. When you upload your image you'll get a bunch of options (code and url) for different applications - blogs, forums, thumbnails, etc. Best IMHO is to copy the direct link url near the bottom of the page and paste it between the [img][/img] code in your post
www.ohshot.com - simpler than imageshack, upload images from your computer and get a link
Or sign in for an image hosting service - e.g. Photobucket, flickr, etc.
