need imagemagick help...

Is there a way to pass imagemagick an image as a variable from a php page and have it return a thumbnail to the page as a variable?

I'm building a fairly robust image gallery system that stores images in a mysql database. I have the users submit their images through a form. So the full size image is still in a variable waiting to be written to the db. But I want to create a thumbnail FIRST (in case it fails, I don't want it to make the db entry). So I want to have image magick return the thumbnail to my $thumbnail variable. Once that is successful, I will store both in the db.

Dunno if I said that clearly, so lemme know if you need clarification.

You can use imagemagick to do this, but I think it would be easier to use the php image functions to shrink the image and save it as a thumbnail.

One of my sites, www.dubr.com allows members to upload images which are then automatically resized into thumbnails using copy_image_resized();

To use imagemagick, I would pass it command line commands [which can be tricky] with a php script.

I don't know the syntax off hand for imagemagic, but once you figure out how to resize images from the command line, just have your script do the same thing via one of the following: system(), passthrough() or exec()

again, not sure which one will work.

I have a script that will make thumbnails with imagemagick using exec()... The thumbnails actually come out quite nice.

I looked on php.net and they talk about imagecopyresampled() ... People say it works well. But Can anyone give me a snipet of how it's used? On my site, people submit images through a form and I need to store the image and a thumbnail in the db.

One thing I'm not sure about is, how do I deal with different file types? If someone uploads a gif, how do I tell the function it's a gif... I suppose I'll have all my thumbs be jpg, so that'll take care of that, but how do I know what type of image I'm pulling from the db when I pull out the full size image? Gunna need some help on this part.

Thanx.
