Panel hooks and the resize() function make this easy. This function deletes the original image and cleans up extraneous thumbnail files to save disk space. https://gist.github.com/samnabi/f4ecb351f2ec2bd596e5 config.php <?php // Copy this code into your config.php file // Replace the …

You could change line 12 of the code above to add another condition to the if statement. Change this: if ($file->type() == 'image' and ($file->width() > $maxDimension or $file->height() > $maxDimension)) { to this: if ($file->filename() != 'dontResizeMe.jpg' and ($file->type() == 'image' and ($f…

Maybe turn this into a plugin? Then it would separate logic from config.

Thank you @samnabi , this is very helpful.

You can also use function shrinkImage($file, $maxDimension = c::get('images.maxWidth', 1000)) { that way you can set the max. width for every environment .

hm it seems that dontResizeMe.jpg is still resized: kirby()->hook('panel.file.upload', 'shrinkImage'); kirby()->hook('panel.file.replace', 'shrinkImage'); function shrinkImage($file, $maxDimension = 1000) { try { if ($file->filename() != 'dontResizeMe.jpg' or ($file->type() == 'im…

@lukasbestle That’s it. :slight_smile: I also tried with @Pascalmh exemple: function shrinkImage($file, $maxDimension = c::get('images.maxWidth', 1000)) { but get an error : Parse error: syntax error, unexpected ‘(’, expecting ‘)’ in A:\UwAmp\www

The issue here is that you can’t call functions in default values. It has to be: function shrinkImage($file, $maxDimension = null) { if(!$maxDimension) $maxDimension = c::get('images.maxWidth', 1000); ...

Perfect, thank you all, for explications and solutions.

The resize feature is great. I just wanted to add that it’s also possible to limit file sizes in the blueprint. It will not resize, just prevent too large images from ever being uploaded. files: width: 150 height: 200 https://getkirby.com/docs/panel/blueprints/file-settings
