Image block - Crop by the client in Edit mode
OPTION 1 by code (i wrote only the last line of code):
src="<?php echo $ih->getThumbnail($page_thumb, 600, 600)->src ?>
OPTION 2 -
In edit mode "image block" --> checkbox the "Resize Image" - dont crop the PIC only set max w - h
"THE BIG PROBLEM" - Most of the time the client/designer want to position manually the cropped area (like in the file -->edit pic)
How to solve this?...
One option is for the client/designer to use the image editor.
Another option is creating a custom block that uses a custom thumbnail. This custom thumbnail can use the thumbnail system for non-destructive cropping and editing.
