Al has provided you with very clear instructions regarding your Avatar, Moshe.
If for any reason your Avatar fails to upload, it's most likely due to the size of your photo. You can always email me your photo and I will upload it for you. I'll also return the modified photo to you for your archive, with instructions for future use, should the need arise.
To find my email address, or any other member's email address, just click on the envelope below my profile picture (Avatar).
