The idea of ​​the big pictures and limitations of hosting

Once again, I ran into the problem of restrictions of virtual hosting on the size of the download file. Often, the problem manifests itself when users cannot upload a photo taken directly from the camera. And if by a miracle we managed to load it, then PHP does not have enough memory to process it (decrease).

I can offer a large-scale solution to the problem.



It creates a single service that works transparently for the user. My idea is based on using the resources of a single service for processing large images. Let's say we have a website where you need to bypass the hosting restriction:

1. In the form of sending a picture, the link to the handler on the service side is written in the action attribute.
2. In the same form, several hidden fields are created that describe the image processing parameters (dimensions, quality, etc.). A separate field is created to tell the service where to post the processed image.
3. The service receives a request, processes the image, taking into account the specified parameters and posts the processed image to the source site.

Sample form:







The idea can be modified. At a minimum, add support for sessions, but the essence, I hope, is understandable.
