Example

For each images we need 3 sizes of images as following convention:
1. <snake_case_image_name>_<image_regular_width>@1x.png
2. <snake_case_image_name>_<image_regular_width>@2x.png
3. <snake_case_image_name>_<image_regular_width>@3x.png

Example: lets say we have an Academia Logo.png with regular size of 100x30, then we have to create 3 images as following:

1. academia_logo_100@1x.png (100x30)
2. academia_logo_100@2x.png (200x60)
3. academia_logo_100@3x.png (300x90)
