They all look good. I recognise some of the elements
to post photos right click on the picture, choose 'copy image location' and then paste that in between the image tags that appear here when you choose 'insert picture' from the options above your reply text box (it's the picture, 2nd from the left).
That's for Firefox, for IE you need to right click the photo, choose properties and copy the image location from there. Pretty sure Chrome allows you to do the same as Firefox. No idea about Macs but my iPad lets me copy image location as an option when I click a photo. There's a thread hereabout posting photos somewhere in the 'about forum' board (I think).
