If you can see anything related to the rear dropout on the picture that you posted (yes in full size) you have got good eyes.
You said that you tried different wheel but not if they worked or not.
Can you tell which part of the axle that gets stuck, is it the axle itself or the aouter or inner nut.
Some frames have removable insert in the dropouts, if your frame is one of those are they seated properly.
