the yellow triangle, and corresponding light yellow bar across the pic is from an automatic resizing of the picture (a setting which can be changed in your user control panel) clicking on the bar will change to the original image size.All the pictures in my build forum have a small yellow triangle in the upper left corner with a ! in it and a note on the bottom left corner saying "report this image" When I click on the note it says something about inappropriate material.
I was looking thru this thread for an answer and see the sample pics posted here have the same thing!
What's that about???
the report image is a different link, used for reporting images that break cf guidelines, or if youre a pansy and find something offensive
