[theme-reviewers] Image Resizing

[Rahul Bansal]

I completely agree with your point - "Suggesting to everyone that they have to run a plugin every time they decide to change their image sizes seems to be fraught with the risk of being lynched."

I had similar situation and my theme was approved. 
As you have nicely explained the use case, you should't face any issues IMHO

So it is imperative to have some kind of resizing functionality that works above and beyond the native WP resizing capabilities (which I am anyway using). This is where the above script comes really handy, but needs a good few modifications. To cite a few examples:
> I have made the method work for external URLs, plus the size parameters are actually based on the registered sizes and not "GET" parameters.
> The resizing is only invoked if an image of "intermediate" size (the fourth parameter of wp_get_attachment_image_src()) is not returned by the post thumbnail functionality. Also note that due to this means I cannot use the_post_thumbnail by itself, but I have to use wp_get_attachment_image_src(), which is called by wp_get_attachment_image(), which is called by get_the_post_thumbnail(), which in turn is called by the_post_thumbnail.
> The result of the above is a seamless transition (hopefully) from my previous approach that used TimThumb to the current approach. The reason I have gone this route is so that users don't freak out when they see their images have not been correctly resized. Suggesting to everyone that they have to run a plugin every time they decide to change their image sizes seems to be fraught with the risk of being lynched.
