No, our PM software doesn't support uploading attachments (photos) from your computer.
If you're a contributing member with album photos, you can insert the image address of an album photo using the
button (located above the message text window).
After you've loaded the photo to your forum album, right click on it and copy the image address. Create the PM that you wish to send, click the image button (explained above) and paste the album photo image address into the pop-up window field labeled "Please enter the URL of your image". The image will be placed in the message body where your cursor was located.
If you use a photo hosting site that allows it, you can link image codes in the message text body the same way. Photobucket recently blocked 3rd party hosting unless you pay $399/year, but there are other free hosting sites out there.
