There is a super image converter for commandline: ImageMagick
,it has a lot of image convertion tools.
You can install it using brew,just brew install ImageMagick
(if you are using mac with brew) ^_^
- First, I bet you must resize your imgs,here is the example
mogrify -resize 640x480 *.jpg
- then you can convert them into a gif:
convert -delay 20 -loop 0 *.jpg myimage.gif
