Topic: Only seeing some thumbs

I have uploaded the original files, without any additions. I am even still using the default picture. I am using SmartFTP v2.0 and am getting the following error uploading some of the images.

[21:47:27] SIZE PIC00074.jpg
[21:47:27] 550 Can't check for file existence
[21:47:27] File size check (SIZE) failed. File not found or permission denied.
[21:47:27] PASV

This is only occuring on some of the images, as nine of the 25 images DO show up.

What seems to be the problem???
