Bash Script Image Resizing with ImageMagick

This script is used for creating different sized images that integrate nicely with social media websites. I became quite tired of using finder to resize and resample images for web development projects. Hopefully this tool can help you out as it helps me.

Installation

git clone https://github.com/mavieth/image-resizer.git
cd image-resizer/

Running

• Drop images that need resized into project root
• Run script
• Profit

sh build.sh

Sharing

These are sizes used for sharing posts on your site or for linking things such as Twitter Cards and Facebook Cards.

General Sizing

These are sizes used in general (not entirely sure what that means) on various social media outlets.

Adjust Cropping

ImageMagick has well documented parameters that can be interchanged in this script to provide different functionality. (keep image aspect ratio, crop, add background, etc.)
