I have lots of interesting pictures I could put on this forum when appropriate, but I have not been able to figure out how to do attachments. Actually, I know the mechanics of doing the attachment itself, but I don't know how to make the picture come out big enough so anybody can see it. I always get this message that says the picture can't be more than 100,000 bytes (whatever that means.

All the rest of you seem to know how to attach big, beautiful pictures. Somebody, PLEASE, tell me how to do it. And please keep the explanation really simple.
