Hello!
I am no developer, but I think I have a nice idea for a workflow. I think you know the problem when you have a high resoution picture and want to upload it on facebook or somewhere else, but it's simply too big. I like it to compress a image not by changing the quality of a jpg, but by changing the size of the image till it's short enough. I'd like to use "preview", because I don't want to start a new application if it's not necessary.
So my dream workflow should open an image in "preview and downsize the image till it's about 1 MB big an then export it as an jpg in an extra folder on the desktop.
I hope you understand what I mean. Maybe there's someone outthere who wants this workflow and is able to write a script for this.
Greetings from germany!
