Signature Image Maximum Filesize
 

I have the signature settings under Registered Users set as the following:

Signature Image Maximum Width (pixels) :500

Signature Image Maximum Height (pixels) :350

Signature Image Maximum Filesize (bytes) :10000


And yet members still seem to be able to place larger pixel pictures in their signatures. (They are not in any secondary groups)

Does the Max Filesize override the pixels?

Also does the bytes refer to GB or MB?
