Imgur.com & imgbb.com are 2 that a lot of people use.

"And..OMG is that porosity in that rod?!?!"

I'd clean and dry the rod and look again.
Probably do some dye pen/Spotcheck/Zyglow inspection.

That cluster a bit down from the piston is suggestive of a weld repair on a porous or internally or externally filthy casting, or welded on a day with high humidity etc.

Thanks. Just tried to find a quick site. Please recommend a photo hosting site and I will change them.

I use Google photos.

FYI, the cyber security SW in my two PCs block and alert of the OP's pictures in this thread at www dot minpic dot net. My work computer does the same.

Make what you want of this. All I can tell is that this is highly unusual in my experience. I have never seen this before with speed-talk posts.

If I google the site www dot minpic dot net, it is blocked as unsafe.

Beware. And keep your AV SW up to date.

Can you share which software you are using?

I use Bitdefender and it did not go off.

I'm using MalWareBytes at home. Work PC runs McAfee.

I've learned one very important thing in this entire experience - I'm building my own engines from this point forward! There have been multiple issues. Next time it will be my fault!

Thanks!

It is good to have a goal...

the engine runs on alcohol?

It is possible the bore finish was too smooth and not enough oil was allowed to "cling" to the cylinder wall and lubricate the works.
