Cloud mining sites seem so Ponzi to me, is there any company who shared out some 'real mining' photos to prove that they're really doing this business? Any proof about it?

cex.

most of the cloud mining companies are ponzi
not all but most of them
only few legit companies are there, but i wonder if any of them sharing their hardware pictures or videos

Did they share it? Can you share the link please?

Any of the cloud mining services from the ASIC manufacturers:

AMHash
Hashnest
KNC Cloud

I am truly amazed how many people buy some sites.  I looked hard at like that ltcgear, I cannot see how people pay for it.  I wanted to believe with people saying they times it by certain amounts, getting free shares sometimes.   I just could not bring myself to pay without proof of equipment.

And I could be wrong a lot do seem to love ltcgear.  I could be missing something.

The proof is on their website. They have specific machines whose performance is measured and published on their website. They also allow for people who own their GH/s to withdraw their GH/s for a physical machine of equal capacity (plus shipping)

i think a legit cloud mining site will allow you to transfer your mining power to an external pool and mine whatever coin you want
also you will able to see how much hash rate you getting
others are just ponzi sites

This is probably the best way for a cloud mining operator to prove they have actual hashpower. I don't think it would be that difficulty to implement and am not sure why they do not do this.

Around the time that ghash had ~51% of the network hashrate they said they would be implementing this feature in the near future, but it doens't look like anything ever came of this promise.

You would not be able to mine any coin that you wanted, only coins that have the same mining algo of the contract

i would choose the asic producers, skip pbmining and all the other ones.

if they dont produce hardware, its prob a ponzi. im more into hashnest since its bitmain and always has hardware, they also give you the hardware eventually.

I heard that they're cutting much from maintenance, what is the reason for that? More cut means ROI comes late...

Have a look here:

As you  guessed, the vast majority can safely be assumed to be ponzi scams. 
There are few legitimate offerings out there, and even fewer (if any) that make any financial sense.

They do have a somewhat high level of maintenance/electric costs. I have no idea why they charge so much (maybe the physical machines are located in areas of the world that have generally higher electric costs, but this would be speculation).

You are correct that the higher maintenance costs will result in a lower ROI (if any)
