Thank you for looking into this for me! It installs now, and the settings page actually lists my custom image sizes, which is an improvement on every other plugin I’ve tried. I am getting errors when I try to upload new images now:
Warning: imagealphablending(): supplied argument is not a valid Image resource in /public_html/wp-content/plugins/smart-watermark/image-editor.php on line 15
Warning: imagesavealpha(): supplied argument is not a valid Image resource in /public_html/wp-content/plugins/smart-watermark/image-editor.php on line 16
Warning: imagecopy(): supplied argument is not a valid Image resource in /public_html/wp-content/plugins/smart-watermark/image-editor.php on line 19
These repeat a few times, I’m assuming for every image size I have set to be watermarked.
I wasn’t really sure whether to respond here or open a new thread- technically, the installation issue is resolved.
