How can I limit the size of profile image uploads?
What should those limits be?
In K2 Media Manager, Parameters, there is "Enforce memory limit (in MBs) for image processing"...but there is no help as far as how that relates to file size.

Elsewhere, in the documentation, it seems to suggest that files above 8MP may require more than some limit...

It seems that my users are getting errors uploading files larger than 2 MB, most seem to be in the 5 MB range.

What are my options?
Thanks.

Hi. The setting you are mentioning has to do with memory limit and not with the image file size. This is there for users getting the memory limit related error. The max file upload size has to do with the file size and can be changed in the php.ini file of your server.
