Changes to hook image_make_intermediate_size

[stephanreiter]

Currently we have the filter 'image_make_intermediate_size' in WordPress that allows plug-ins to rename/move the intermediate image file after it was created. In order to modify the image, e.g. to add watermarks, plug-ins first have to explicitly load the image although it was in memory just moments ago.

Changing the filter image_make_intermediate_size to receive the image handle in addition to the filename would allow plug-in creators to write more efficient code by reusing the image resource before it is destroyed. This can be accomplished by relocating the filter invocation into the image_resize function.

Perhaps it would be better to add another filter before saving the new image in image_resize(). This would allow more processing while the image is still in memory and also catch instances where the function is called directly.

The filter can't be used for getting the image resource because of the changes in #6821. Closing this ticket since you now can create your own Image Editor. If there is something I missed please create a new ticket with details how it should now be implemented.
