Batch Processing #31

Can you please make a way to simply drag and drop multiple PNG images into ImageAlpha at once to compress?

I've tried ImageOptim and honestly PNG Gauntlet for PC is a LOT better giving me smaller files sizes and better quality gradations. PNG Gauntlet shows me the % compressed for each and every PNG image. I would like this for ImageAlpha.

Please make this, Thanks!

Lossy mode in ImageOptim uses pngquant, which gives the same compression as ImageAlpha (or better, because ImageOptim also adds AdvPNG and ZopfliPNG on top of that).

Both ImageOptim and PNG Gauntlet have PNGOUT + OptiPNG, so they should give about the same file sizes (PNG Gauntlet also uses DeflOpt, but it's a minor, abandoned tool that adds only about 1% more compression).
