upload/captcha problem

[eluser]ebuoe[/eluser]
After development on my local machine i was able to upload pictures and my captcha image was showing,but now after hosting the site on the web,the captcha image isn’t showing and i am unable to upload files.


is this a CI problem,or is the problem from the host provider..

Well it's not a CI problem. Mine is working fine on local and hosted so...
probebly your host provider which would be silly to since it's just uploading...
but it's not a CI problem

I think you might've problem in u'r PHP codes. It'll be easier for us to detect the error if u show u'r codes with us.......
