# easyimages-uploader.sh - A shell script to compress and upload images to an EasyImages instance.
|
||||
#
|
||||
# This script takes a local image file, compresses it into WebP format,
|
||||
# and then uploads it to a specified EasyImages server. The resulting
|
||||
# image URL (in Markdown format) is copied to the clipboard.
