Arduino Fio / nano pro 8Mhz + JPEG Serial Camera

I’m testing diferent hardware for jpeg serial cameras and the problem I’m getting is with arduino Fio and nano pro 3.3v 8Mhz is unreadable jpeg
that I found is when i try to get a picture with 8Mhz arduino, the output serialprint has a lot of errors and can’t be converted in jpg afterwards
So I didn’t try to decrease value of bauds for the camera, there’s any other way to capture images with this 8Mhz microcontrolers?
