Generate thumbnails with GD or ImageMagick?

  • Hopefully, I’m just overlooking something and you guys will laugh at how simple my problem is.

    As far as I can tell with my current WordPress install, my images get sized via CSS based on numbers that I can modify when posting. When displaying a post, CSS tells my browser what size to display the image at, but the image itself is never altered. What I’d like to do is generate thumbnails at the time of my post (using GD or ImageMagick, based on the same numbers) and display the thumbnails in the post itself, giving a link to the full-size image.

    Right now, I’m running into problems such as stretched images, having to do math to prevent them from being stretched, and loading an entire 3 meg image, when a 100k thumbnail would suffice.

    Is there a setting I’m missing somewhere to do this? Maybe a plugin? I’ve searched and searched, but must be missing it. I could write a plugin to do this, but I’m hoping I won’t have to.

    Thanks guys!

  • If you’re uploading images from within the admin dashboard, you might want to change the sizes in wp-admin in Settings under Media, something I somehow overlooked for probably the first 6 months of using WordPress.

    I sometimes use TimThumb to resize images.
