Ok I only use notebooks so...

What type of error message or report are you receiving from PsychCentral when you fail to upload a pic?

The photo may be too large. If so, go into your photo shop or editting program on your computer and reduce the size/quality/pixel whatever so it fits here. (I cannot use any of Canon digital photoes directly because they are 18mb!)

I haven't check recently (I'll put it on my list to do) but I have never been able to upload more than one photo at a time.

Let us know... I'll subscribe so I receive email when you do.
