Picture size hosted feature service

[roialgavish]

Hello,

I am using the Collector for ArcGIS with a hosted feature service, I am using picture as attachments

and the size is getting very large, I was thinking of building a python script in order to resize the pictures. I have two questions:

1. Is there another way to solve my picture size problem?
2. Can I run a script form my computer that will change the size of the picture on the hosted feature service?

Thanks allot, Roi.
