 I hope I am in the right place here to suggest two enhancements for WP

 From my perspective the most used image of a post is the post-thumbnail. I
 use this post thumbnail quite often in different sizes - for teasers,
 related posts, sliders etc. From a performance perspective I always want
 to deliver the image in the correct dimensions. No 1600px image in a
 related post section where the image is 200px wide etc. I am struggling a
 bit because I often work on websites which have a lot of pictures in their
 posts. When I add a new image size its always relevant for all images
 which are uploaded to WP and often they are not necessary. I do not need a
 200px wide image of 20 images which are used in the post - I only need it
 for the post-thumbnail. From that perspective I would like to have another
 function than add_image_size - for example: add_post_thumbnail_image_size
 which is only triggered when somebody selected an image as the post-
 thumbnail. This will save space on the servers as well.

 Sometimes I have the case that I need the attachment ID of an url that has
 been uploaded. For example: I delevoped a plugin where an image can be
 chosen, the input field is a text field for a URL. In that case I need to
 determine the attachment ID to have access to all the necessary WP
 functions. In this case I built my own function that does it, but I think
 it will also be a function that can be helpful if it is integrated in WP.

 Looking forward to your reply.

 In order to always get the image in the correct dimensions which are
