[wp-hackers] url image resizing

[Braydon]

When using add_image_size with over 15 sizes when no image would use all
of them is when it seems not ideal, especially when needing to change
those sizes after they have been uploaded. The Dynamic Image Resizer by
Otto might help in that type of situation. Though there doesn't seem to
be a clear way to delete resize images without using bash. I find the
image_resize, with conditional, and the plugin WP Image Resizer by
Frank, to be preferable and flexible, and would have cleaner code. Since
the parameters of the image would be in the same place that the image is
being used, as usually add_image_size is used someplace else, such as
functions.php or another initiation point.

I'm in need for image resizing from JavaScript, which could be probably
handled with a series of predefined increments set in PHP, so as to not
have too many options resources exposed. Having every size available is
refreshing, though.
