I have a directory with 10,000 JPEGs. I made a mistake while generating the files and now some are 720px  480px, but they should all be 448px  336px. The directory contains both the too large files and the correctly sized 448px  336px. They need to be all the same size, so I need to scale the 720px  480px images down to the correct 448px  336px.Every file must be 448px  336px.Since there are 10,000 files, it is difficult to check each one to see which are too big.Is there some way to use ImageMagick or a similar batch tool to selectively only resize those wrong-sized images?
How to resize only the missized images?
