@Florian, as the title suggests.
ifgreater and ifless fns would be useful.
On beatports pages any 2021 release and probably onwards have 500 - 8192px images.
You can derive any size if you replace 500x500 with 1500x1500 and so on.
So I was wanting to check for a value greater than 2020 to get this added to the scripts.
Here's a 2021 release at 2000x2000px: https://geo-media.beatport.com/image_size/2000x2000/c6ba445a-14c8-42bb-abde-8db33b682eda.jpg
Can you try with this internal build? My tests are green, it should be working:
https://download.mp3tag.de/support/0621794E-BA8C-4BBF-A84D-ACED48444553-3521/mp3tagv305bsetup.exe
If it turns out fine and is helpful, I'll add it to the next dev build.
Yes, this is brilliant and would love if this could be implemented in the next dev build.
It's the only way I can future proof my script without doing lots of if's.
I doubt Beatport will be going through their back catalogue to uprez those artworks.
This would be a very helpful function.
I would be glad to use this in my scripts. 
This is now available with Mp3tag v3.05c.
