Hi all. It is possible to receive pictures from a webserver (POST) then send back them after some modifications? How to do so ? Ideally we are looking for creating a remote service that listen for POST calls. As our server is on Linux (PHP) we can't create a Linux CGI, and our ISP don't allow this. We are looking for a remote service for our program. Where to start ? Bob Back to top theo Guest Posted: Tue Sep 26, 2006 6:04 pm    Post subject: Re: resize images.

If the images are big (more than 1500 pixels wide) and the memory is limited (16MB), then the server produce an error and everythings goes wrong. I actually use the GD library for resizing (the link you sent) and I'm having this problem as the library uses the memory to resize the image.

OK, but I really don't understand your initial question. What is "a remote service that listen for POST calls" ??? What's a "POST call" anyway? Do you mean HTTP method "POST"? But then PHP should handle this easily. Back to top Bob Bedford Guest Posted: Tue Sep 26, 2006 7:07 pm    Post subject: Re: resize images.

What's a "POST call" anyway? Do you mean HTTP method "POST"? But then PHP should handle this easily. Maybe I wasn't so clear, sorry When a user upload some images on my website, then they are resized. If the original message is too large (in resolution) then the server fires an error message and the script fails. My idea: if I detect uploading of too large images (having their size) then I'd like to send the images with a POST HTTP method from the server to my program (running on our XP server), then my program will detect entrying images, resize them then return (also with a POST) to a page I'll create in PHP that will save the resized images where they should be. Remote service that listen for POST calls is the program that will receive the HTTP POST form from the server, with the images. POST call is like a form on Internet where the method can be POST or GET. It isn't so important as I can set the value in my form in POST or GET anyway.

Are you serious? Simple solution: Change to a decent ISP! Yes I'm serious :-) The actual ISP is one of the best here in Switzerland, so I won't change just for one limitation. The problem is real for many people around (look at google for this problem) and going to a dedicated server only for that is a shame. Also I found to be an interesting problem to solve and would be interested to know how can be managed. Bob Back to top theo Guest Posted: Tue Sep 26, 2006 7:45 pm    Post subject: Re: resize images.

Quote: Also I found to be an interesting problem to solve and would be interested to know how can be managed. But then it's still mainly a problem on the PHP side. If you can't install anything on your ISP's server, then you have to use PHP to "forward" the data to you. Maybe curl helps: http://ch2.php.net/manual/en/ref.curl.php Your "Remote service that listen for POST calls" is a webserver Back to top Bob Bedford Guest Posted: Tue Sep 26, 2006 8:31 pm    Post subject: Re: resize images.

Anyway I still need help in the delphi part as I've never tried such thing. Bob Back to top theo Guest Posted: Tue Sep 26, 2006 9:49 pm    Post subject: Re: resize images.

You need a second webserver at yours, doing the same thing as the ISP's but with no restrictions. Back to top theo Guest Posted: Tue Sep 26, 2006 10:20 pm    Post subject: Re: resize images.

I don't like to spread my private email in the ng's/forums for spam protection and other reasons. And I don't want to be contacted privately by people I don't know. If it's necessary, there's always a way to contact each other.
