Create thumbnails from external images?

[Guldstrand]

I need some advice / tips for a function that can create thumbnails (2 different sizes) from an external image (url), then save the file name/path in mysql.

 

I´m working with a small portal for webcams, and I need to be able to download cam images (usually. Jpg) from users own websites, and then create thumbnails of them.

 

Preferably any function that does not require too much of my server (RAM, CPU and bandwidth).

You can use wget to grab the image from the remote server by specifying the URL

 

then you use functions from the GD library to build your thumbnails from the original

I made this code, you will have modify it some to get it to do what you want it to do:

But it grabs an image from some web site and displays it. To save it, you need to add/Change these values:

 

Change "NULL" to a file name for a jpg:

imagejpeg($thumbImg, NULL, 100);

 

Add a second parameter for a gif:

imagegif($thumbImg);

 

Change "NULL" to a file name for a png:

imagepng($thumbImg, NULL, 9, PNG_ALL_FILTERS);

 

Hope this helps!
