[anantchai]

I dont want to let user upload a thumbnail image ,so I try remove the input for thumbnail file in member_uploadform.html  but failed.It said "security ..."

Any help'd be great appriciated.

Remove the input code completely:

Code: [Select]

<input type="file" name="thumb_file" class="input" />

Do not add any hidden inputs or something with the same name ("thumb_file").
