resizing images on the fly

[graham23s]

Hi Guys,

 

what im trying to do is get random inages from mysql and display them in like a "random profile" box, but i was trying to keep them all roughly the same size, so basically grab them from mysql and:

 

<img src="images/image1.jp2" height="$height" width="$width">

 

so basically it just displays them in the correct ration WITHOUT saving them

 

is this possible at all?

 

thanks guys

I do this on my server, but since its my server I just use image magick's convert command.  My code looks like this:

 

	
function imgResize($img)
{
exec('convert -size 125x125 '.$img.' -resize 125x125 '.$img);
return true;
}

 

Where image is the full path to the file.

Hi Mate,

 

that worked a treat, is magick better/worse than GD can you also save resized images with it?

 

cheers

I wouldn't be the right person to ask if it is better or worse, but its obviously easier and there aren't really any downsides.  The portion after the -resize argument is where you are telling the command to save the file.  In the example I gave, I am just over writing the existing file.
