Generated images should be optimized

[jelen07]

Terminology

• uploaded image - image from the user's device (mobile, notebook, etc.)
• original image - a copy of an uploaded image on service storage (AWS S3, app filesystem, etc.)
• size - the physical size of the image (in kB, etc.), not the dimensions

Consider the following UC's.

1) The original image

• When uploading some images, the original image (without filter and modificators) should be the same size and quality as the uploaded images.
• When uploading some images and filters or modificators are applied, the original image could have a different size.

2) Uploading the largest image

When uploading the largest version of an image, smaller thumbs should have a proper (relative) size to its dimensions.

3) Uploading the small one image

When uploading a small dimension image, bigger thumbs should not have a bigger size.
