Cyndi, under the edit menu should be an option to resize the image. Go there and resize to a max of 600 pixels on the longest side (I usually stay at 550). By default, it normally has the box checked to keep the image proportional, which is what you do want. It should be set to 72 dpi, which is what your monitor displays. Save the image using the "Save As" option and give the resized image a new name. When it asks how much compression to use, take the middle choice (Adobe Elements uses a 1-12 scale, I use 5-6). Most of this is from memory, but I believe it should head you in the right direction.

If you are a Sams Club member this is usually a good place to buy Elements at a lesser cost.
