I had a look through at some of your recent photo posts and the cards are more vertical than horizontal in sizing. Standard tarot cards tend to be tall and thin, rather than wider in their shape. The forum seems to really want to turn them into a vertical column. I had a go with one post at dragging them around the post, but didn't save it at the end, just had a go at experimenting with it. You can move the photos around and drag them but the forum really doesn't seem to put them in a line. I think this is something where you have to change the sizes, like make them smaller in display size and maybe it will put them next to each other in a row. If you click on a pic in the post, you can change the size of the photo in the post (and people can click for the full size). It's an automatic displaying by the forum and I found it really tricky to make them a row. It really wants to make them longwise, there isn't an easy solution for this one I'm afraid.
