Hello! Try looking at the
Universal camera settings - there are 2 streams Xeoma takes from the camera: for preview and for archiving. Preview stream is usually lower quality (this
reduces CPU load), yours is probably 352x240.
Sending Email module takes the
preview stream for pictures and videos.
Note that this is true for the vast majority of modules that aren't
Preview and Archive.
So, if you need high-quality pictures for
Sending Email - just put the main stream as preview in the
Universal camera module.
One last thing - we do have the use of the archive's stream for this module on the Development Plan.
