Image size issues in Zoho creator, can we compress and resize somehow before upload or even after upload

Is there anyway we can resize the images being stored in Zoho creator.?
We have a number of reports that utilise the photos and images we store and that report produces PDF reports. These pdf reports are getting to larger with the huge images being stored by default by zoho creator.
