Is that a question to @TCC ?
@TCC obviously didn’t realise that ESP’s don’t use AT commands when you flash them with an Arduino sketch like Blynk.
How to upload photo to here? I hit the “upload” can not upload photo. I like to show u the USB TTL , and i connected the GPIO0 to ground make as flash or programm mode. The rest pin are connected to the USB TTL. only the GPIO0 and groung is joined together.
When you make a post there is an icon for file upload.
Sure! 
Are you sure you wired it correctly? Or it is a descriptive shortcut. Certainly you need to wire the CH_PD and it is safe to pull up the RST ( I’m not sure if ESP-01 handles it correctly)
I do not see any upload file icon. I only see the word “upload”. But the " upload" unable upload also. I had uploaded once photo before using the word"upload" . But now can not.
I can see the photo you uploaded at Virtual pin referencing physical didn't work. Can help? so you should still have the facility. Users gain additional rights not fewer rights.
Try sending the image to me by PM if you still can’t upload it.
How to PM, I’m newbie here. Not so familiar to the facilities here.
Click on my avatar etc.
Still you can (?) drag and drop images (to the message area), but the usual ‘upload’ should work too. Weird…
I’m using phone here , not computer.
This is the USB TTL i using.
Wasn’t there a post a couple of days ago saying you need some hack for these to work?

I have connect the GPIO0 to ground.
For esp8266 communicate to IDE, i have disconnected from GPIO0 with groung.
OK, GPIO0 short only during powering the board.
Then flashes correctly, right? So what is/was the problem? IF it flashes the chip, THEN it can communicate to computer.
But i enter AT command no respond.
