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
There's also this thread http://www.orchidboard.com/community...ng-photos.html
(which I haven't read, but should be helpful, I hope)
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.
