Dude, these are BMPs and I gave up on them after they passed the 7 MB mark while they STILL were loading.
Try submiting them again, using png format instead.
Edited the links, it's better now.
The sheets got resized and are unusable now.
Try breaking them into smaller sheets instead, and try again.
Try using imageshack or making smaller sheets. Photobucket doesn't resize the sheets and leaves them the size that you meant to upload them as.

You can still use Photobucket. There is an upload setting to resize up to "1 megabyte file size". As long as you aren't uploading a BMP (which are huge), it should be possible to upload a large PNG and still not be close to the limit.
Seriously. I have quite a number of images taller than 768 pixels (tallest allowed for free users) because I set my upload to "1 megabyte file size" and an animated GIF that's over 1 megabyte in size because I set my uploads to a set dimension setting at the time.
Use any hosting site you want. But I figured you should be aware of a possible solution if you want to use Photobucket. Both it and Imageshack have their strengths and weaknesses.
Now we are talking. Good job, man.
