(as first - thank you for all your help several years ago, and second - please
apologise me for my clumsy enlgish)
so, preface: some users on my photo related site sometimes enter (link) giant
photo in their post or coment, and while I was writting new bbcode for my
forum, I have got idea to check size of linked pictures to scale them down if
needed (matamethic of that part isn't written in folowing code and would not
be a problem).
and now, the problem: function getimagesize() worked fine while getting data
from my other domains on same server, I tested it with some from other servers
and worked fine... but just until I called that function from other function
in my semi-finished page. All I get is "Warning:
getimagesize("http://bla.bla./bla.img") [function.getimagesize]: failed to
open stream: No such file or directory in my.script.php on line 3". But - you
will be able to see that same function (getimagesize()) *is* working on the
same page called alone... what went wrong? what am I not seeing?
I will paste two scripts (some commnets and variables have been written in
croatish, hope that that wont be a problem), the testing one - where function
after submit button isn't working (script includes whole yet written
formatings), and the first one (coding) where I coded that functions...
people interested in solving my problem can see scripts in function and their
source (if my newsreader won't post code properly):
