Sitewide Image File Resizing
I have a large image site that was recently reformatted. The old format had images 600 pixels high. The new format has images 300 pixels wide. The images were rescaled to 300 pixels, but not resized. To reduce download time I'd like to use Digital File Pro to resize on upload about 1,500 pictures.
What's the fastest way to do that in DFP?
