Please help!

I can't upload properly. Just uploaded 299 pics from camera to computer. Went through ok but were so enormous that I reformatted and re-sized. Emails wouldn't go through and pb was taking about one hour per photo!! So I then took them straight from the card to the computer which was much quicker, resized them again. PB is still taking around 20 mins per photo, it's ridiculous, I've never had this problem before. I just can't upload them. 😞
