Is there a ratio of compression for a file size. I'm asking because I'm not a Gold Member, but I've looked at a cover which was shown at about 250KB and when I've downloaded it it was the file size stated. I just downloaded a cover which was shown as 909.7KB and I ended up with 69KB. I know I wasn't going to get the full size but there must be some sort of limit that they get compressed to. I once downloaded a large size file and ended up with 18KB.
Can't there be a limit set that no large file be compressed below 250-300KB? I know you can go on about bandwidth but really!
