What is 구워서?
Wow, that seems to be it, thanks!!!!
Hey Nixie, it looks to me like this is probably talking about burning the photos (onto a CD or something). The verb 굽다 is most commonly used when talking about grilling, baking, or burning food, but it can also have the meaning of "사진을 CD로 굽다", that is, "burn images onto a CD".
The text is a bit unclear as to what she is specifically doing, but the implication seems to be that she burns all the hundreds/thousands of photos onto CDs then goes through them/sorts them out after the trip is over and she is back in Korea.
