How To Use Resized İmages in view?

[eluser]Unknown[/eluser]
Hi
There is a problem about using dynamic resized image in the view pages..

For example all of my pictures are 400x300 and I want to every image show the thumbnail 100x75 and when the any image clicked 400x300 image shows the popup.

I got the image resized but how to use this image in anypage_view.php

Be careful I dont want to save thumb. ı want use original file and create dynamic resize and use the pages..

You could write a controller that outputs the resized image, for instance by setting the dynamic_output to true while using the Image Manipulation class. And then you could use it like this (with a controller "images", a function "thumbs" and an image "image_name.jpg"):

Code:

<img src="&lt;?php echo site_url('images/thumbs/image_name/jpg'); ?&gt;" />

Though I wouldn't recommend this, when creating lots of thumbs it will consume loads of megabytes of memory and most servers won't like that. It'll also slow your pageload considerably.

If you're going to displaying a lot then you should probably consider saving them...
Then next time the page is visited you can check if they have already been created and save the memory.

Entirely agree with jacobc.

I just wrote a gallery system (web front end to plug into KPhotoAlbum), but not using CI. I tried gd2 and imagemagick functions, and for some things had to drop out to system() calls too. It was just infeasible, even on a very low traffic site (my own) and a reasonably powerful server (dual-core, 4GB) to call up relatively modest sized files (5MP and 7MP JPEGs) and convert them on the fly.

I ended up developing a very basic cache system and generated thumbnails, medium, and large images. Works a treat and wasn't especially difficult to construct. My cache management system is pretty easy, though, as I'm coming from a known collection of all available images (KPA uses an XML backend) and built a small admin function that will go through to check for stale cache files. But really, the thing flies compared what it was like doing it dynamically.

You should run a few benchmarks for resizing your images.
