Re: trouble with forcing output to be cached

The image is already written to a file. i wrote "..CREATION.." as an example, because there is no difference do you write and read, or create. If you pass something through PHP, it will append it's own header HUH :( .. so not so simple ;[ i guess that it is impossible to find a solution here, but i would be interested in any information about this simple trouble, and maybe request for feature for something like remove_header() function.. Any other ideas :) ?
