Here is a correct issue 25 for Super Magician Comics.  It appears every time I try and update the image CB downloads the old one and replaces the one I added.  I disabled automatically download images feature and that allowed me to replace and submit, but as soon as I turn it back on it downloads the old image again.  Perhaps something you should account for in future updates.  How to leave the "automatically download images" enabled while also allowing for a local replacement.

Maybe support a custom suffix, like 25-local.jpg, which supersedes 25.jpg for presentation (and submission) if it exists.

Also, Issues 34, 44, are incorrect.  Attached are low res, but correct images I swiped from GCD.

What version of CB do you have installed? This was a problem but was fixed (at least for me and another customer) recently. I am currently on b1557.

I have 1557.

Is the correct cover scan you are replacing larger than the incorrect one that automatically downloads?

If it isn't, this could be the problem.

If it is, you may need to contact support to see why this wasn't fixed for you.

I'll send them an email.
