I just noticed a lot of photos that are over 150k.

The server should not allow this. Can you point me to an example?

Good point, and I just got your message. I'm looking at the pictures now and I'll let you know what I find.

Tim,
I just looked at the pictures you listed in your PM, and the confusion is what I expected. Unlike in most applications, where kilo means 1,000, a kilobyte is defined as 1,024 bytes. This stems from the fact that computers count in binary (base 2) and that 2 to the 10th power is 1,024.
The actual file size limit is 150*1024 bytes, or 153,600 bytes. The server will reject a file larger than that at submission time.

So 150k=153,600 bytes. Am I the only one that didn't know that?
Thanks for clearing that up. Now I have to put my votes back in line.

No problem at all. Actually it's not that common knowledge... you're far from the only person who doesn't know that.
As for voting, we ask that you don't vote a photo down because you assume that a rule was broken. Instead, please submit a request for disqualification and cast your vote with the assumption that all rules were followed. We (the moderators) will research it and disqualify the photo if appropriate. I mention this because in past challenges some photographers have done some really innovative stuff that was completely within the rules, and they got hammered on the scoring because people assumed they cheated and piled on the ones.

The same math applies to MB - it's actually 1024 KB or 1024 * 1024 bytes. And 1 GB = 1024 MB or 1024 * 1024 * 1024 bytes. What makes it worse is that disk drive manufacturers always use the wrong measurements. They say that 1MB is 1 million bytes and 1GB is 1 billion bytes. It even says so in the fine print on the box. This allows them to claim that their drives are bigger than they really are, and it keeps them from having to confuse consumers with the facts. ;)

Greetings,
1024 as in 1 KILOBYTE pertains to memory, 1000 * 1024 = 1,024,000 bytes in one MEGABYTE of memory ... Disk megabytes are measured as 1,000,000 bytes... Always been that way ... Always has been always will.... If Drew and Langdon are using 1024 as a denominator for file size on disk they are using the wrong measurement...

A disk kilobyte is 1,024 bytes (the disk physically stores in clusters sized in powers of 2). Long ago the HDD manufacturers started sizing disks in decimal based MB and then GB sizes (powers of 10) along with a footnote explaining that's what they did. They did this so they could call a 39MB drive a 40MB drive.
You may note that Windows calls a 1,023 byte file a 1,023 byte file, and a 1,024 byte file a 1K file.

Hi Terry,
Guess I'm too old school... Fifteen years ago 1,000,000 bytes was referred to as a megabyte of DASD (Direct Access Storage Device) when we used to bill our customers by Megabyte/hour for IBM 3380 disk storage space on our mainframes. I once asked our performance expert why we did this. I thought 1024 * 1000 equaled a MEGABYTE. He told me a 1024 * 1000 measurement was used to represent a megabyte of IBM memory and 1,000,000 bytes represented one MEGABYTE of there disk. Guess he was wrong?

They did it because they made more money that way.
