If you still get a black background and you are merging the image returned from this function on to another image then heres the problem. It took me days to figure this out and I hope it saves someone else lots of time. imagecopymerge() does NOT preserve the transparency, that is what makes it a black background, not this function, instead use imagecopy() and it will work perfectly.</p> <p>There are also 2 typos in this function if you get the version from GitHub, $trnprt_indx should be $transparency and $trnprt_color should be $transparent_color</p> For those who get a black background, this works perfectly with images saved as PNG 24 rather than 8.

There are also 2 typos in this function if you get the version from GitHub, $trnprt_indx should be $transparency and $trnprt_color should be $transparent_color

Is that due to the way the original PNG was created or is there something I need to tweek with your code. Unfortunately I don't know a lot about working with images like this. Any help is greatly appreciated.</p> <p>Thanks!</p> Ok, so I’m uploading PNG files and they are resizing correctly but coming out with a black background instead of transparency.

As you can probably guess, I am not all that familiar with GD.</p> This function is good and all, but I have been looking for 3 days now on how to fill the transparent portion with a specific color.
