One more experiment. Attaching 1500 pixel photo. Last was 1200 but came out resized to less than 800 pixels.

No problem uploading 1500 pixel image but resizes to 764 pixels the same as the 1200 pixel upload above....but the forums now look like they will upload larger photos without the user having to resize....I think. I'm done messing with this before I screw something up. I'll consult my expert webmaster first chance I get.
Thanks Vern, for getting my attention. As "administrator" my limitations are sometimes not the same as non administrators in doing ordinary tasks and I'm unaware of problems encountered unless somebody tells me.
(By the way....the photo is of the USS Independence, LCS-2, made by Austal USA in Mobile, Alabama. Austal is an Australian ship building company.)
