Larry, let's take another look at this......
We allowed Andrion 9 images on his initial casting and the difference between 8 and 9 is slight. However, with 2 images left - he could conceivably reach a total of 11 and the difference between 8 and 11 is fairly significant. And given that Andrion at 17th level would get a minimum of 6 images each casting, he could conceivably stack 2 castings of the spell for a minimum of 12 images.
Let's not be so quick to give up the cap. Since we allowed nine images, I'm fine with making that the new max. Otherwise, I suggest we keep the total of 9 for this battle and use the cap of 8 for future occassions.
BTW - In first edition the spell produces 1-4 images. No cap is explicitly set, but intention seems to be toward keeping the number of images under control.
