[SL Viewer 2.6 or 3 or Phoenix crashes at preview screen when I try to upload a valid image.]

For several weeks, every time I try to upload a 1024 or 512 24bit JPG file, then the viewer crashes on the preview sqreen when I click on "Upload"   I have tried viewer 2.6 , the latest 3.xx, and the older Phoenix viewers and all crash.  I have uploaded hundreds of texture images in the past without problem.  I have no idea what has happened !  Help please!

[Why my Avatar invisible to a friend, using regular Phoenix, when I use Viewer 2, 3 or Phoenix?]

For 2 months now , one of my Avatars is INVISIBLE to a person on my Friend's List.   He is using Phoenix 1.5.2.1185   He can see that I am on line but cannot see my Avatar standing beside him.

He cannot see me if I use SL Viewer 2.4 , the latest SL viewer 3.* or even if I use Phoenix 1.5.2.1185.  He can see my other Avatar just fine.   Could this be a friends list setting or maybe one of my old Groups settings where he is a member?

Open to suggestions!
