- yep even than 12 x 24 inch mat. With the latest updates (ie after 0155) if you have the default cursor on ie 1 inch and then add the image and try increasing it will stop when the width or height touches the mat sides.You can move the image off the mat but will not increase beyond.
A way to get larger image is to initially set the cursor at a very high value and add the image. Then the image will be large. You can then decrease to the size you want. Note once you decrease you cannot increase. To increase you will have to start over again
