Hi,

I this possible ?


How would this work? In order for the server to do the
resizing (which I guess is what you want, as that's where
Pillow is installed), you'd have to upload the full file, and
then allow the server to resize it - in which case, you're
uploading the large file anyway, so you'd have to remove the
file size limit to allow grapelli to upload that size file.

If you want to resize the file locally before uploading - why
would this be a feature of Mezzanine, which is server-based?
Can't you just resize the pictures yourself using any photo
app on your local computer/device, and then do the upload?

There are 3 ways of doing the resize :
1) Server side. I have to authorize bigger files to be
uploaded. Then, how do I resize the image ?


It looks like this is the best option.
So, how do I resize the image when it is uploaded ? 


Use Pillow to do the resizing
(https://pillow.readthedocs.io/en/5.3.x/ )  but I'm not sure
where in the Mezzanine code to put this - possibly as part of a
filebrowser or grapelli fork?


Sure, Pillow is the way to go.
But where do I put the resize code ?


Mezzanine generally doesn't resize images on upload, instead opting to 
resize images server-side when they're first requested. The code for 
doing this resides in the template where the image is displayed, see: 
http://mezzanine.jupo.org/docs/utilities.html#thumbnail

Thanks for the explanation.

For client side image resizing I use Uploadcare (https://uploadcare.com/).

2) Client side. This is feasible with javascript. Mezzanine is server 
based. This does not mean the client is completely dumb. If it was, 
why use javascript libraries (on the client side) ? So, how can I 
achieve client side resize ?
3) Using a local app. The person that will enter blog posts has 
difficulties using computers. The simpler, the better. I prefer to 
avoid this method.
