Not happy with the existing solutions/plugins to generate photo albums in WordPress I decided to create my own based on a BASH script and some PHP code.
- Upload the photos you want to a folder, example:
- Because this folder doesn’t contain any index.php or default.html or similar I enabled “directory browsing” so you can see the files, in this case the photos, and click on them to see them. To do so create a file called .htaccess and put inside:
+Indexes
- At this point you just have some folders with big JPG files inside, I decided to automate a process which creates thumbnails of this files in a subfolder called “.thumbs”. It is designed to search all JPGs in all the subfolders. My example worked in Debian in the folder where the images are:
find . -type f | grep -E "jpg|JPG" | grep -v "/.thumbs/" | awk '{ run="convert -geometry 150x150 " "\"" $0 "\" ";
file=$0;
sub(/(.*)\//, "", file);
folder=$0;
sub(file, "", folder);
system("mkdir " "\"" folder ".thumbs/" "\"");
run=run "\"" folder ".thumbs/" file "\"";
system(run);}'
- This will create the thumbnail (max 150 pixels wide or long) in /.thumbs/ subfolder. It basically finds all JPG files and run this command for each file found:
convert -geometry '150x150' "./Alex day 5/DSC_6395_resize.JPG" "./Alex day 5/.thumbs/DSC_6395_resize.JPG"
- Finally you just need a PHP code which reads the file list in the folders, and generates the links to the files showing the thumbnails, like in here: http://abadcer.com/photos/Alex day 2/
<?php
if ($handle = opendir('.')) {
while (false !== ($file = readdir($handle))) {
$jpg = strpos($file,"JPG");
$jpg_low = strpos($file,"jpg");
if($jpg == true | $jpg_low == true) {
echo "<a href=\"$file\"> <img src=\".thumbs/$file\" /></a>\n";
}
}
closedir($handle);
}
?>
