Running into the same issues with uploading images and sizes on the wp media library. The sizes do match what I put in the media settings. Then when I go to a post to insert a image all the sizes are screwed and under sizes it only shows 3 of 4 available sizes. Thumbnail Medium and Full Size no large?

I am running:
WordPress 2.8.5.
Server: Apache/1.3.37 (Unix)
PHP: v5.2.3
GD: bundled (2.0.34 compatible)

I went through high and low and still having issues.
I deactivated all plugins. Reactivated 1 by 1. – No luck

This page has been updated for WordPress 2.7 – It still has the thumbnail size option built-in, but its position has moved to Settings -> Media

I got the permanent media php file to work, but if i ever upgrade, I lose all of those settings. I cannot get it to work for my wedding photography blog as a theme. Any suggestions?

Thank you, thank you, thank you!
Finding that line and changing it, unguided, would have been well beyond my comfort level!

Hopefully you will update this post to include changing the default thumbnail, medium, and “full” size image uploads for WP 2.5?! This would be greatly welcomed.

Excellent, thanks! I figured it would be in there somewhere but you saved me having to dig through all the code to find out where exactly.

Please forgive my stupidness, but where exactly do you find this wp-admin folder?? Is it on my server?

WordPress 2.3

Open /wp-admin/includes/image.php and look for the following code:

$max_side = apply_filters( ‘wp_thumbnail_max_side_length’,
128, $attachment_id, $file );

The number specified here (128 by default) is the maximum size of either dimension. Just change this to whatever you like.

Thanks. This was easy. I agree that it would be nice to implement a faster change in the options somewhere. I could see myself forgetting to change this the next time I upgrade, which I’m sure won’t be too far off.

In WP 2.3, can you modify the code in order to set both the height AND width?

It might be better were you to use a plugin for this, rather than mucking about within the code. There is actually a plugin already written, available at http://www.shiftthis.net/wordpress-thumbnail-size-plugin/ . This is not mine, just something I found. I’ve used it from v2.0 on (including 2.3.1).
