Photos not uploading intermittently

Hi,
I was trying to upload JPG images to my gallery today morning
This is the gallery
http://tanveer.smugmug.com/Travel/Ladakh2009/Favorites

By default I first used the simple uploader to upload 5 images.
Now I have an Asymmetric DSL connection, and the max download speed I see is 100KBytes/s, ditto for upload. this is at night.
Daytime, the download speeds go down to 64KBps and upload to around 30KBps

Now when I used simple uploader to upload my 5Meg JPG image, it was showing me 10Mbps, and the image was uploaded in less than 10 seconds!
Whooosh. No Errors also.
But when I clicked on gallery, nothing there, empty.


Finally I had to use Send To Smugmug.
At first try it uploaded 3 pics, with 2 saying failed.
Only when I retried it could upload.

Is there some problem going on.
finally after 3-4 tries I was able to upload all the pics, and ended up with duplicates also.
