@Dr Sliptinschit,
When a picture is too large to fit on the a2k screen, instead of:
Code:[img] [/img]
Try this:
Code:[img width=900] [/img]
You can try other widths.
width=960 is the full width of the a2k screen.
width=900 will let the picture fit in a quote box if someone chooses to quote your post.
Sometimes an even smaller width will keep a picture from overwhelming the rest of a post.
