When you upload inages to RCU, the server is supposed to resize them to 640 X 480 or thereabouts. But the image server crashes or locks up sometimes and the picture will be full size which is sometimes very big. Frustrating to me but nothing I can do about it. Once the image is big, it is that way even after the server is rebooted.

With the WYSIWYG editor you can copy and paste pictures also. These transfer at what ever size you copied.
