tikirat, you need to have a certain post count (I can't recall the amount) in order to post images. My suggestion would be to open a free Photobucket account and have them host it for you and insert them into your posts that way. That's always the way i've done it.
welcome, and for the pics, you can either get them from your album in your garage. Or use photobucket.com and copy the url in the image box, to do multiples i haven't figured that out just can do one at a time.
