vBulletin Manual - Upload Smilie

On this screen, you can upload one image at a time through your browser for use on your forum. To do this, both your web server and PHP must have permission to write files to disk. If they do not, this will fail.

Note:

The directory that you are trying to put the file in must be CHMODed 777. Consult your FTP program documentation for how to do this.

If you don't know how to do that you can also use the alternative feature to add one or more smilies through the Add New Smilie manager.

Uploading a single new Smilie (Smilies > Upload Smilie)

Filename
Click on the [Browse..] button and select from your hard drive the smilie you want to upload.
Title
This is the title you want to give to describe your smilie.
Text to Replace
This is the replacement text for the smilie. When a user types this text in a post, it will get replaced with the smilie image.
Smilie File Path
Type the path of the smilie directory. An example would be images/smilies. This directory should be readable and writable by the webserver (usually CHMOD 777).
Smilie Category
This drop down box will have all the possible smilies categories - select one to add this smilie to this category.
Display Order
If you know which order you'd like to give to your smilie you can enter it here, this is an optional field. If you don't know what the display order should be you can leave this field empty, you can always change it later.

When these details are entered press the [Upload] button to add the smilie to the selected smilies category.
