Change error message for picture import
The error message for importing an image that is too large needs to be more verbose. Right now it is something like: cannot be larger than 1920. It should be something more like: cannot be larger than 1920 pixels in width.
I blinked a few times at the error message. 1920 is awful small for a file size and I was able to import images larger than 1920 bytes in size.
