In order to use the PHP function imagecreatefromjpeg() within a Docker environment, you must install the GD Library, which is not included by default in some PHP official images. This requires modifying your Dockerfile by adding the command 'RUN docker-php-ext-install gd'. After making this change, it's important to rebuild your Docker container using the appropriate docker commands ('docker-compose build' or 'docker build'), ensuring GD is properly installed and configured.
To enable the GD Library in a Docker container, you need to modify the Dockerfile to include 'RUN docker-php-ext-install gd' and then rebuild the container.
Once you add the GD extension command to your Dockerfile, remember to run 'docker-compose build' or 'docker build' for the changes to take effect.
