werid GD problem

parawizard

it seems like when i have my server running with GD enabled my one php file outputs GD stuff and another php file exactly the same code DOES NOT output. It just outputs werid characters to the browser. its very odd i cant figure it out any suggestions?

weekender

how are you calling each file? going directly to it, or calling it in an <IMG tag?

if it's sending out random chars, that'll be the image data - it's just that the header isn't being sent to the browser properly

all files are send with a header called Content-Type, with values such as text/html, image/gif etc etc and you need to send this for the browser to know that it's a file, not a stream of text.

i was thinking maybe i needed a header. but also the other file doesnt have one, but maybe the key is that IT DID have one before. does it register headers into the file or something>? because one works (never had a header) one doesnt work (used to have a header) seems odd to me 😕

i was wondering if you could give me anymore wisdom in this matter would be great 🙂

edit

is it something todo with browser remembering the header type>? or is it something to do with the acual file>?

weekender

at the top of the file put in

header("Content-type: image/gif");

(or image/jpeg if it's a .jpg)

then open it in the browser...

parawizard

yes i understand headers 🙂

header("Content-Type image/png");

but i was wondering when i take the header off and open it again is it the browser that remembers the header because it was opened before? or is something acually telling the browser of a previous header in the file?

weekender

the only thing i can think is that maybe the browser cached the image. That way, it would save the image locally with a filename such as 32944824.png - ie it would save it as a png, and so 'know' that file type.

Can't explain it otherwise - have you got it working?

parawizard

yes i have with the header it outputs to the browser 🙂 and if i take the header off it still outputs to the browser now. I wonder i should test this i have to get some free PHP space first tho im hoping to get my own server box this month
