Make comments or posts show latest first

I want when people comment or post for it to show up top like a blog…i think. I’m now to this stuff but I have users posting pictures and when they do I want it to appear on top not below. Can you tell me how…also is there any way to limit the final displayed sizze of the posted pic? The plugin for posting images has no options for it -thank you and great theme! The site is

There is a setting under Settings - Discussion inside WordPress dashboard that reads like this:

Comments should be displayed with the [older/newer] comments at the top of each page

It does exactly what it says it does.

I don’t have any suggestions for file size limit as it is not controlled by theme but by this plugins, so you should ask plugin developer what you can do it about it.

Let me know if this helps.
