Hi,
Currently I only have a way to add an image via a url is there a way to upload an image like I see here.
Thanks
You will need to download the SP Uploader plugin.
Here is a guide in case you do not know how: http://codex.simple-press.com/codex/plugins/using-plugins/
Oops yes I just saw that. Thanks for your quick answer
What would you recommend as a maximum size for images and video
thats up to you… I think we use 100k for images… I guess I would try a couple meg for audio/video… but just play around and see if folks are having issues uploading theirs… the point is to not let folks go crazy… its your disk space 
there are distinct permissions for uploading images, video and other files… only give folks you want to be allowed to upload the specific type, the permission to do so…
