how do i find a tmp.... png in my doc? epub kicks it out
 

Hey... i'm trying to convert my document to an epub and it keeps coming up with the same error message:
1. ERROR: quickstep-guide-to-realizing-your-dreams (1).epub: The file tmp_813dac77b7a9bd62e2e2c07168939117_3Jvb2P_html_m 6ea46af0.png does not appear to be of type image/png

how can i find out where this is? i have 11 pics in this document. i removed them all and then reinstalled them. it's apparently not liking one of them.

can anyone help?
either way, thanks for reviewing!

What are you converting with? Meatgrinder/Smashwords? Some readers don't support png, so it is usually better to use jpg or gif.
You are sure they are png images?
