Open a ticket with the help desk to get the limits. We do not discuss them in the open forums. You can use N/A for any of the fields you do not have information for. Link at top of page or in my signature.
Ah, sorry, thought you had an account here. I have no idea of the server configuration, I am a moderator and don't have access to that information sorry.
Welcome to the forums Winston
No there are no images needed to be loaded. If it's not working I'm sure if you opened a ticket with the help desk they would check it for you.
I use this on three different sites and it works as advertised.
Sorry Dan, not something I've ever played with. But couldn't you do another file (better quality) and name it the same as the one that's currently there and overwrite it?
