It might be a trick of the light, but at the moment it looks like pins 1 & 2, 3 & 4, 5 & 6 and 7 & 8 are connected to each other (through the bread board).

Could the problem be a firmware that's on the ESP? This is my first time using Arduino IDE to program it.

According to your picture, it seems that RST is left floating ...
It must be pulled-up !

(BTW, any firmware already present doesn't matter since it is the booloader which is in ROM that will take care of uploading your new firmware.)
