Do multiple castings of mirror image stack? Is there a limit on the number of mirror images one may have of oneself at any one time?
According to the spell description, the maximum amount of images is eight. Nothing in the description precludes multiple castings stacking, but you'd still have to abide by the maximum number of images.
In general, the same spell cast multiple times that has the exact same effect does not stack.

I rarely see people indicate where that "rule" comes from. Have a source? Or is it an only an urban legend? Typically where I do see it cited, it is only applied to numeric typed bonuses. I do not believe I have ever seen anyone in authority apply it to this situation. Does not mean it is not out there.

There is a section in Chapter 9 that deals with multiple effects on a single target.
I believe this is applicable here: "Same Effect More than Once in Different Strengths: In cases when two or more identical spells are operating in the same area or on the same target, but at different strengths, only the one with the highest strength applies. (PFRPG 209)"
Essentially the mirror image with the most images applies and you ignore all others. For example if a mage had mirror image up and only one image remaining. He could cast mirror image again his single image is replaced with the normal 1d4+1 per three caster levels.
Core Rulebook pages 208-209 in the section on Combining Magical Effects.
In the case of Mirror Image this paragraph applies:
Same Effect More than Once in Different Strengths: In cases when two or more identical spells are operating in the same area or on the same target, but at different strengths, only the one with the highest strength applies.
If you cast Mirror Image and get 3 images and then cast it again and get 5 images you have 5 images, not 8.

What if the source is different ... say a ninjas with shadowclone who uses a scroll of mirror image?
I would say that that is the same source.
Shadow Clone (Su): The ninja can create 1d4 shadowy duplicates of herself that conceal her true location. This ability functions as mirror image, using the ninja’s level as her caster level. Using this ability is a standard action that uses up 1 ki point.
Thus, it is Mirror Image and does not stack with Mirror Image. Take the best.
