Newbie : Resizing Images with PHP and Mogrify

[phpmaddog]

Hello Community :

I have been reading around about image quality on the net and I have decided to use server-side power to resize images (mostly JPG) pulled from a database without damage image quality and then displays it in web browser.

What is happening is :
I have a website that the User uploads images of any size to a database called images.

Now because that image that was submited to the database will be used in several part of the website and in different sizes I would like for when people looking at the site when ever the image is retrieved from the database is procesed by a scrip using Mogrify then outputs it to the web browser.

I have been reading but i have find codes that ONLY resizes permanently at the upload process then save them in a database.

I would like say a 500x500 picture.jpg uploaded to the database be retrived ( by web browser ) converted ( without the original being changed ) and the puts its output to webbrwoser as a 150x150 image without image being distorted. I found lots of code outthere but are simple ones that just loose the qulity of the original size of the image

Is there such task that can be acomplished ? I ask to start with ImageMagick Mogrify because my webhosting supports it.

Please help I will apreacite the effort.

Thanks.

If disk space isn't an issue, you would be better off scaling the images and saving them. It will take a lot more overhead to scale on the fly.

But, if you must ...

You can create a script that does this:

Open the image
Create a new image from the opened image
Close opened image
Resize created image
Outputs it to the browser (i.e. header('Content-type: image/jpg')😉
Trashes created image

I don't have time to write this our right now, but it is pretty easy. Again, I would store the resized images instead though ... unless they are dynamically generated of course.
