i saw post #1088066 come up in my subscription notifications via esix extend just now (why it alerted me 8 months after the post, i have no idea.) and the description there says the deluxe, higher resolution version of the pics in the Saddle Up! 2 art pack were free to be uploaded.
does that also apply to the first art pack as well? cause if it does, i probably have a lot of pics i could replace with superior versions.
