In my image I have some black I wish to make transparent (as I then merge the image onto another), I guess this is 'alpha keying or 'chroma keying'?
So yeah, is there like a imagepngtransparent() function that accepts a image and a color (or just uses black) and then makes all of that color on the image transparent??

Please, write clearly with proper structure. Double spacing makes the text feel un-jointed, Capitalizing Every Word Means People Stop Before Every Word Sub-Consciously Which Is A Pain In The Backside, and use code tags! (The right most styling box).

Assuming you wish for all the colour to be transparent, you would be looking for the imagecolortransparent function:
PHP: imagecolortransparent - Manual
int imagecolortransparent ( resource $image [, int $color ] )Resource:
PHP: imagecolortransparent - Manual
