This script travles a directory structure and creates thumbnails for each image and video (flv, avi, mov)
This requires packages Imagick and ffmpegthumbnailer installed, this can typically be done with a package manager for the OS.
Base for search is hardcoded as /data/images
Thumbs are places in a subdir called "thumbs/200pxHigh - If the Height Parameter is 200. eg. "thumbs/800pxHigh - If the Height Parameter is 800
Image names are kept, movies get a ".jpg" appended
This is closely related to the me-image - Image lightbox with Confluence style, me-image - Image lightbox with Slimbox2 and me-image - Image lightbox with fancybox macros
Executing the script:
./makethumbs.sh Height
Sample
./makethumbs.sh 200
Parameters:
Height | Height of the thumbnails |
|---|
Source of the Script:
#!/bin/bash
IFS=$(echo -en "\n\b")
Height=$1
ThumbsDir=$Height"pxHigh"
LabelHeight=10
if [ $Height == '' ]
then
echo "Missing Height Parameter"
exit 0
