No, as it would allow to create a collision, violating the goal of a
cryptographic hash.

You must have misunderstood what I was asking ... I'm not asking for a
hash that creates the same result from two different images.

OK, then your problem is that a hash doesn't omit any information about
the hashed content, so you'd need to do brute-force searching.

However - I've got stuff at this end that detects them ... (see the
e-mail address above).

So then: why do you do such stupid modifications? It's just a harassment
for the people willing to reply.
