I find the easiest way is to post as attachments - when you click on the attachment button (paperclip), it opens a window to browse your files - select the pic from your files, then go to the next if you have another and do the same - then you choose 'upload' from that window - this will post your pix as thumbnails which will show bigger when people click on them

Let us know if you still need help. I'm not the best at explaining stuff, but will do my best, but I'm sure others will also be able to help.
