Unfortunately you have to split them and yes they look like two different worksheets.
Many people here add "name of worksheet (1 of 2)" or something like that in the title. �They also add some informatrion in the description, so we know to look for the other half.
You can reduce the size of the images:�
a) Double click one of the images in your worksheet
b) on the image tab press "Compress"
c) Select "all images on this document" and "for web or screen"
d) Voila.
Hope that reduces the size enough.
There are other ways to reduce the size of worksheets, someone did a tutorial about it, but I can�t find it. �Maybe someone will post the link... See told you.
