I keep getting "mode not supported" error now when I try to post image (charts).  I tried resizing within the post feature as well and still the same error message.

I wasn't getting this error message until a couple of days ago (earlier using same image type and no resizing) and was able to post my charts without any problems.  The image type is .PNG.

Any ideas on what the issue may be?  Is there a maximum image per thread that has been reached?  I doubt it but thought I would ask just in case.

Thanks
Serge
