Range: 50'/level
You gain a dim impression of the activities around any object bearing your face or form and can also project your consciousness into one such object at a time, allowing you to observe or even interact with nearby creatures. This spell allows you to leave your body and subconsciously monitor the immediate area around any depiction of your image whether one, hundreds, or even thousands. Each such image ...
You may, at any time, choose to fill one specific image within range with your consciousness. While inside an image you lose the ability to monitor any other images within range but remain fully aware of your own body's surroundings. Your body is defenseless and helpless (always failing any saving throw) while your consciousness is filling an image, but you can return to it at any time as an immediate action.

In the spell description, range restrictions are explicitly noted for the 'fill one specific image' option in the spell, but no mention of range is noted for the 'dim impression' option. Between that and the mention of 'one, hundreds, or even thousands', I get the strong impression that there is no range limit for the dim impression option.
Is this the case? Normally, I wouldn't worry about it, but I'm running a kingmaker campaign, and it's not unreasonable to assume that the party is going to start minting their own coinage...with the image of the ruler stamped on one side. If so, I want to be prepared.
Just discovered this spell myself this weekend (had never really looked too closely at the APG spells before now). I love it- I've long wanted to make/create something like the Trumps from Zelazny's Amber series, and this spell fits the bill!
Anyway, as to your question, my guess would be that the range is the same regardless. I'd think the "dim impression" bit is simply that- while using the spell, anything with your image on it registers as a dim impression to the caster (sort of like hearing whispers or seeing something at the periphery of your vision), but that if you would like, you can actually project your consciousness into a specific image- focusing your attention, as it were- as opposed to simply just taking in random and unfocused sensations from all of the images at once.
