This script was made on Ubuntu Linux
Are your camera's image file sizes getting larger and larger and make downloading from the Internet a little too slow?
Try this script ( resize_images.pl ) to resize your jpg and png images and bring back that quick page load to your web page.
Run this script before the perl-cgi-images.pl cgi script whose instructions are listed below...
This may be good time to backup your images out of an abundance of caution
Place the images ( jpg png ) you would like to display in a public folder such as the following...
/var/www/MySite.net/public_html/MyDirectory
Then place the resize_images.pl script in the same directory as your images
You may need to install imagemagick for this script to run
To install imagemagick on Ubuntu Linux try the following...
$ sudo apt install imagemagick
You can also build from source... see https://imagemagick.org for instructions
A helpful page to install imagemagick with instructions to add png support found here
Try the following after installing imagemagick to see if your image type is supported.
$ identify -version
When run, this script (resize_images.pl) will create or overwrite thumb images named "thumb_*"
Run the chmod (permissions) command as follows to give permission to run the script
$ sudo chmod 755 resize_images.pl
Run the following command to create thumbnails (May require sudo)
$ sudo ./resize_images.pl
If it works you will see a generated list of image files converted to thumbnails
It can take a few seconds per photo to process the image to a thumbnail.
This script is for someone (a photographer for example) who would like to display web pages of resized images paginated into separate sheets/pages.
Very good for sharing photos with family and friends.
This script requires a web server with a cgi-bin that runs Perl.
Place your images ( jpg png ) in a public directory (as mentioned earlier) on your server that has public http access such as /var/www/YourSite.net/public_html/YourDirectory and run the resize_images.pl script.
You may have to change permissions on image files with something like..
$ sudo chmod 664 *.JPG
Images to be displayed will be sorted alphanumerically with six images per sheet/page as the current setting. (You can change this number if you would like.) . Arrange photo file names alphanumerically to determine display order when running this script.
To unzip the github zip file use Linux "unzip" with the -d flag to upzip into your prefered directory.
Change location of unzipped directory to something like the following
$ sudo unzip Perl-Web-Images-main.zip -d /usr/lib/cgi-bin/
Next, move unzipped folder to your cgi-bin gallery's directory.Something like...
$ sudo mv /usr/lib/cgi-bin/Perl-Web-Images-main /usr/lib/cgi-bin/MyGallery
Give execute permission to the perl script.
$ chmod 755 perl-cgi-images.pl
Change name of perl file perl-cgi-images.pl to index.pl
$ sudo mv perl-cgi-images.pl index.pl
See notes and other instructions in the Perl script
