Your question lacks the details required to provide anything more than a guess as to the answer. I do not have any problems uploading pictures into MySpace, Facebook, or any other social media site. Then again, I don't try to upload anything but JPEG, or PNG. I also keep the size of the photo to less than 2 meg, Most of these sites use HTTP to transfer the data. This usually limits the transfer size to files less than 16 meg.

It may be that you have some settings turned off in your browser such as Javascript. You may also be looking in an empty directory in the browse dialogue box, try looking at other folders and see if images show up.

One more thing, make sure the images are in acceptable formats by the site you are uploading them, if they are not, they may not show in the browse box at all.
