Interesting to say the least neh Susan-chan? Anyway, folks to download a picture (assuming you have enough credits), look to the left of the screen. Under your login name there's a section called OPTIONS, if you have enough credits, you can click on the Download link (a "credit cost" is reflected in brackets for downloading that file).
Anyway, I would like a bit more detail on the credit system? Do you still get charged a credit for trying to download a file and then the server times out? What do you get credit for - uploads, comments, what? And finally, is there a value rating on the amount of credit you get? Does a Poor high quality scan count for more credit than a equally hiqh quality (cleaned up) but lower resolution? Many questions for the FAQ Me thinks!
