You don't really need that John, let your good resolution intact (it won't be a big sized image anyway) and just use the height parameter to size it as you like but in fixed nr of pixels like I suggested before to John(n8ur). It works much better and no need for editing, furthermore the way I su

Hi, Page has the pictures using percentage for width and height parameter and that makes it quite dependent on the browser and window size and aspect ratio. It is really odd to have it that way. John (N8UR), you have: you may go there and replace the line above by: and it will be great lo
