sorry i know these techmical ones arent fun to read but please someone help!

i've a Sony Vaio laptop. i can upload photos from my digital camera (also sony) onto the laptop, and save them. but i cannot then get them onto facebook, i select the ones i want but it just wont even start uploading them -it doesnt seem to like either the type of photos they are (jpeg i assume) or where they are saved (normal 'my pictures' folder.)

any help????? please....i have photos from 2 christmases ago that people havent even seen!!!
