You can change the size of the image in any 2d image editing program like photoshop or the gimp. (There are others) . I save the image from vue in the tiff format (no lose of quality) and then manipulate it in Photoshop and use 'save for web' to get the image to the right file size and pixel size.
I dont know what the rule about images generated by the PLE version is, the moderator will have to answer that.
Good luck
