ok when u save it as a JPG, there should be a little screen that pops up. the box sould say JPEG Options. Go to the section that says "Image Options". There you will see the "quality" section. Next to it there should be 2 boxes. The one on the right should be a drop down box where it should have a list, "Low, Medium, High, Maximum". If you are using Maximum, the file will be big. Try using High, or Medium. Or, right under you will see a line with a small arrow on it. The left of the "line" should say "small file" and the right should say "large file". Move the arrow left or right depending on the file size. You can check how big the file size by looking to the bottom of the "Image Options" box, where it says "Size"
