Image Uploading Error? ("Oops, no images were selected.")

Has anyone else experienced problems uploading images from your PC? I've tried to upload a image from my desktop (110 X 94, 5.24k.) The uploader reaches 10% then returns an "Oops, no images were selected" message box.
 
Am I doing something wrong? I haven't had issues with image uploads in the past here (granted, I've only uploaded two of them here previously.)
 
Thanks for the help!
