It's a strange one this as the forum software seems to resize the pics automatically even when instructed, and shouted at, not to by me.

However, I've found a tick box which seems to be on side so if you now left click on any pic it will pop out in a greyee/bluey box in its original size.

If I can find a way to get the settings back to normal I will. This is added to the 'square away' list.
