A:AnswerHP Officejet 8610 has only Usb 2.0 connectivity. So, you can use any Usb stick for the pictures you want to print from when printing from Usb stick inserted into the front of the printer. The Usb stick just has to be big enough to put the pictures on. Remember, each picture can be aproximately 7-12mb in size. 2Gb minimum recommended.
