Sorry to bother. It seems one of the images I uploaded (this one: Meeting by Creid ), got deleted, though I'm not sure why.
I've got other images deleted, but some may have had text, or such, and I could understand. But this one had nothing bad that I can think of. It's directly scanned from the book, had good resolution, no text, no blur, and didn't undergo any kind of editing.
So, if you could please, explain the reasons, I would be grateful.
Thanks.

Monochrome scans are subject to a much higher standard of quality than color scans. Your scan had panel lines, which are not allowed.

I see. Thanks for the reply.
