I'm trying add the function to add image to a new upload in frontend but i'm really lost

I locate the file when the form is created, /components/com_phocadownload/views/user/tmpl/default_files, i try to put
Code: Select all
<td><strong><?php echo JText::_('COM_PHOCADOWNLOAD_FIELD_IMAGE_DOWNLOAD_LABEL');?>:</strong></td><td>
<input type="file" id="phocadownload-upload-image" name="phocadownloaduploadimage" />
</tr>

I'm really need help with this, sorry for my bad programmer skills and english.
Best regards.
