Now I would like to see if I could make an action for adding album art automatically as well.
Why would I like to do this?
Well you see I have over 6000 albums, all with different album art dimensions. Doing it automatically would minimize both time and hdd writing.
Let me explain how I organize my album art:
Every album has it's own folder. In every folder there can be up to 3 different sizes.
My standard dimensions are 600px, 800px and 1000px. The 1000px is not used at the moment, it's just there for future use.
So now let's get to it. The action I want to do is: If there is a album-art-800px.jpg available the action should change the album art to that one, if not it should choose album-art-600px.jpg. If however there isn't even a album-art-600px.jpg available it should choose either album-art-500px.jpg, album-art-400px.jpg or lastly album-art-300px.jpg
If you could name a function, which will do something like 'If there is a album-art-800px.jpg available', then there would be the chance to do some nested $if() or $if2() construct.
And ... if you care about the large number of image files to process, then you have to organize your work differently. Simply touch less files.
Copy all the best sized images to a file with the same name. So you don't have the need to decide what image file version to fetch and additionally you can save many action calls.
