I am looking to have multiple users edit the same image using the gd library's imagecopymerge function. I am worried that two users might select to edit the image at the same time. The application then merge's the two users images seperately and finally saves them but one overwrites the other and thus one of the users images is missing....

I would like to generate a dynamic image from a script, and then have it load to the browser without being persistent on the server. However, I cannot call this by setting the image's src="script.php", since that would require running the script that just generated the page and its data all over again, just to get the final data that ...

So I Googled and found out how to draw an arc: http://www.php.net/manual/en/function.imagearc.php The only problem is how do I write text $margin pixels from the arc that is curved.

Hi, I use a script (http://www.webmotionuk.co.uk/php-jquery-image-upload-and-crop-v11/) that handles an image and then create a thumbnail. Actually I don't want to store images on the file system but I want to store them in a mysql db in a BLOB field. I could first store the created thumbnail on the fs, store the file in the DB and af...

Most pictures resize fine but for every 10 pictures (more or less) I get jiberish data out. I think it's a picture source. in that data there is always a string...
The PHP code below generates text as a dynamically created image, how would I be able to get the image to only be as large as the text? Thanks. <?php header('Content-Type: image/jpeg'); $text='Test'; $img = imageCreate(200,200); imagecolorallocate($img, 255, 255, 255); $textColor = imagecolorallocate($img, 0, 0, ...
I've got the following function that generates and saves an image based a text parameter. How can I call this in my file? I tried INCLUDE 'outPrice.php'; to link to the external PHP and called it with this command, outPrice($text); To which I got the following response. Warning: Cannot modify header information - headers already...
I am making a dynamic image that parses off of an rss feed. When I do the parsing normally, it displays exactly as I want it to, but when I put it in the image, there are boxes and html characters like ' aren't actually apostrophes. Here's a link to my image as of right now (with boxes): http://img.got-skills.net/advlog/advlogmaker.php...
Having only a valid GD image resource is it possible to find out the type of the original image? For instance: $image = ImageCreateFromPNG('http://sstatic.net/so/img/logo.png'); Can I get the original image type (PNG) having only the $image variable available? ...
Hello! I'm building one kind of system, which simply creates dynamic image from other image. I use imagecreatefromstring(file_get_contents("clown_avatar.png")) to create image and output it successfully, but it messes all the colors on the transparent area. Check out the original image: Click And here is the result from php-file: Cli...
I found this really nice function that receives your desired proportions and resizes/crops the image for you. The function requires ImageMagick to work. Will it be better to cache the image or resize it every time? I'm pretty sure using gd will be slower than caching, but it won't require me to use ImageMagick, and I still haven't succe...

I had an image upload script that worked on my little shared hosting, but just as I switched to Virt Ded, it immediately stopped working. After some research I determined the culprit to be the PHP function imagejpeg() - which was the last bit of code in the script. It allows me to specify null as the filepath (in which case it prints it...
