I'd like to add one image to the bottom of another in php I've this to load the images: //load top $top = @imagecreatefrompng($templateTop); //load bottom $bottom = @imagecreatefrompng($templateBottom); Now I'd like to add them to one picture and display top and bottom together. What way can I do this? Thanks! Use imagecopy : $top_file = 'image1.png'; $bottom_file = 'image2.png'; $top = imagecreatefrompng($top_file); $bottom = imagecreatefrompng($bottom_file); // get current width/height list($top_width, $top_height) = getimagesize($top_file); list($bottom_width, $bottom_height) = getimagesize

Is there a way to prevent the PHP GD image library from running out of memory? If too large an image is uploaded, GD tends to run out of memory, terminating the script. I'd like it to throw a catchable exception or something to that extend, but alas it doesn't. Right now I'm using a cobbled-together script that first issues an ini_set('memory_limit', '128M') , if that works I'm usually all set. Depending on the server configuration though that may not be possible, so I'm falling back on an algorithm that tries to estimate the amount of memory needed (taking resolution, color depth, channels

If I've got a bunch of image resources that I made using the GD library in php, or otherwise a bunch of frames, how can I combine these into an animated gif? I've got an array of images and a frames per second I'd like to add.. I can't use ImageMagick or FFMPEG, and I'd prefer to just use the GD library if possible. Apparently "Support for creating GIF animations is also available." , but I can't seem to find the documentation on how to access this from within PHP? Well searching on Google revealed GIFEncoder.class.php found at http://www.phpclasses.org/package/3163-PHP-Generate-GIF-animations

I'm looking for a finshed solution or possibly some math/algorithms for creating a big image collage out of smaller product pictures? I know how to do it in a square fashion, from same sized pictures with gd/imagemagick but I'd like to have some variation built in. For example, some of the pictures might be slightly taller, and if all are the same size and square - i might want 1 of them take up more space, just to mix up the design. keeping it interesting. the more i think about this the harder it seems to do with a formula. having predefined "templates" for all the possible scenarios isn't

How does one enable (or perhaps I need to install) GD when my phpinfo() output in "Configure Command" says; --without-gd ? I also have nothing in my phpinfo() output "Core" that lists "gd" PHP Version 5.2.4 on AWS. if you are on a Debian based server (such as Ubuntu) you can run the following command: apt-get install php5-gd Then once it is complete run: /etc/init.d/apache2 restart This will restart your server and enable GD in PHP. If you are on another type of system you will need to use something else (like yum install) or compile directly into PHP. For PHP7.0 use ( php7.1-gd, php7.2-gd and

Suppose you have a thumbnail generator script that accepts source images in the form of a URL. Is there a way to detect if the source URL is "broken" - whether nonexistent or leads to an non-image file? Just brute force using getimagesize() or another PHP GD function is not a solution, since spoofed stray URL's that might not be images at all ( http://example.com/malicious.exe or the same file, but renamed as http://example.com/malicious.jpg ) could be input - such cases could easily be detected by PHP before having to invoke GD. I'm looking for GD pre-sanitizing before having GD try its
