[FEATURE] Image Processing Utilities (imageutils) #152
Description
Feature Description
Image processing is essential for modern applications dealing with user uploads, content management, and media optimization. We should extend our library to have image processing utilities.
Use Case
Image processing utilities can be used in many applications dealing with users and content-management.
Proposed Solution
At top level we should follow our library structure.
