image upload max size

In the image upload page, it says the max size is 250kb. Do you really mean 250 kilo-bit, or do you mean kilo-byte? I tried to upload a pic that's 248kB and it didn't go through because it's too big.

PHP Code:


		
			
$FILESIZE=250000;



if ( filesize($source) > $FILESIZE ) { 

  // .. error .. 

}

'filesize' returns the file size in bytes.

kilo != 1000

Ok, now I know what my problem is. My 248KB file is less than 250KB but greater than 250,000B ;)

A little clarification for those who are confused. In computers, 1 kilo does not equal 1000 (10^3), it's actually 1024 (2^10). mega (2^20), giga (2^30), tera (2^40) and whatever's after that also differ from the metric prefixes. So after a quick calculation, my 248KB file is actually (248KB * (1024B / 1KB)) = 253,925B.

Of course, that could be corrected to a "true" 250KB by changing the code so it looks something like this...

PHP Code:


		
			
$FILESIZE=250;



if ( (filesize($source) / 1024) > $FILESIZE ) { 

  // .. error .. 

}
