I know image helper class in catalog module serves good features for image related options like aspectratio, resize, frame etc.. .
My Question is i have images like customer profile image and store image and category images. So, I have to resize these images in various places and to keep its aspectratio for better image quality.
How can i use these functionalities(catalog/image helper class methods) for various images used in magento?
I would like to store these resized images to cache. how can i store this image into cache like product images stored temporarily.
