Someone pointed out recently that "I bent my chainrings"/"The bike store sold me a bike with worn chainrings" threads might be the most common threads in this forum, especially in threads started by self-described newbies. I haven't yet seen one of those threads where the chainrings turned out actually to be bent. That photo of black chainrings against a light background is difficult to interpret, but it sure looks like the usual arrangement of full-length teeth alternating with blunt and twisted teeth as found on brand-new inexpensive mountain bike chainrings.
If something happened during a ride that resulted in shifting problems (reading between the lines of the original post), I'd check the front derailleur, or take it to a bike shop to be checked. It looks as it if may have been knocked out of alignment with the chainrings, and it is certainly not positioned within a couple of millimeters of the outer chainring as it should be.
