Can I try? I'll also get you a copy at loyce.club/other/tmp/ if you email (<username>alenzuela@gmail) me the image.
I've sent it, the format is zip file in Wetransfer link, I think it's better to not make a copy since I don't need it anymore. 
At the moment I have TalkImg configured for uploads of up to 3MB, but the forum only accepts up to 2.5MB.
This is already being resolved at the script level, but it could still take a few months to be implemented.
I can try asking @theymos to adjust the image proxy to 3MB, which would even give more freedom.
It doesn't hurt to try.
