Generated Images are HUGE

[neilbaylorrulez]

Hey there

I am using this task and I noticed that the sprites it generates are quite "bloated"

The source of my sprite is 7 images (7 @1x and 7 at 2x) all of which are under 20kb.

The generated images are:

sprite.png: 780k
sprite@2x.png: 3MB!

To get around this i am running imageoptim which reduces the size to

sprite.png: 12k 
sprite@2x: 22k

Here's the output after I run imageoptim:

/dist/images/sprite.png was: 799.424kb now: 12.362kb saving: 787.062kb (98.00%) quality: 99.9138292%
/dist/images/sprite@2x.png was: 3151.268kb now: 23.051kb saving: 3128.217kb (99.00%) quality: 99.859601%
TOTAL was: 3962.329kb now: 39.186kb saving: 3923.143kb (99.00%) quality: 99.859601%
