Ann and Ray!
Thank you very much you two, but I think I got it sorted now. I never did find out why the pic in my sig was three times the size of the one on my boomspeed page, but I sorted it out by uploading the thumbnails of them to my account instead. They're even smaller than the original Boomspeed pictures, so they work very well. Hopefully that'll put me within the guidelines set down by Jeff and Myr.
Should I need any assistance in the future though, I'll know where to turn. Thanks again and "may the Force be with you". 😀
