permissions question

[25lez25]

To allow a user to copy a file to your server , do you have to change the permissions on the receiving directory ? To 777?
And if so, what are the security risks of changing the permissions?

If this is a major problem, is there a reduced risk if the allowed file type to be uploaded is limited to image files, e.g. gif? Are there any ways to permit uploading and avoid/reduce security risks?

Thanks

about the CHMODing, i think if you do change it it only applies to that directory and the rest remain secure or however else you have set it.

Im no pro, so maybe seek a second opinion. But ive never ahd problems with mine
