Batch Image Resize on Linux
You can easily resize any images in your directory or entry server with help of ImageMagick Libraries if you don't have it you can easily install it by this commands
Ubuntu - sudo apt-get install imagemagick
CentOs - yum install ImageMagick
ok if you installed it, you can use "mogrify" command to resize your images for example if you want to resize all images with jpg extension in directory use this command
mogrify -resize 800×600! *.jpg
this means that all images with extension .jpg will be resized at 800x600, you can change jpg to any image extension you want to resize such as png, gif.......
