No, I fixed this long ago.

I get the bitcoin price periodically and save it in the database and here:
https://bitcoindata.science/api/priceusd.json

Those images get the price from this json above  (if not from the json, they get from the database), not from third party API.

Even with a cache system he would also need to request 50 images  and that will block the page anyway...

I cached the price data already, as mentioned above, so I don't request information from third party. But the user need to ask 50 images , one by one, as this the way the forum works

I don't think the error is related to the number of images and requests. I just created a topic in the Archival board and added a table with only 10 casinos there. There are problems displaying the images and rates there as well. Sometimes they load just fine, other times there are image errors.

The real questions is, how did it work in the past and what changed in the meantime? Could be server-related, a Cloudflare issue, a new setting that needs to be configured, or some other software-related change.
Could the forum be causing the errors? Perhaps it's time to tag @theymos in the discussion and see if he has any ideas.

I still think it's the proxy's waiting time for the server.
Maybe @theymos can give the proxies more waiting time for requests to the Bitmover website.
I don't know, it's just an idea.

Ir is not , because it was working fine like 3 days ago.

Server response time is the same

It's different, what happened to TalkImg was that it suffered a supposed DDoS attack.

From the looks of it, someone is trying to make money by spreading attacks on services and the like, somehow linked to the forum. I say this based on some feedback I received from other users.

Even so, this will not be the case. It was probably some configuration change, perhaps an update (?), but we still can't understand what it is.

Just checking back to see if there has been any development on this particular issue? We discussed it last month but it seems like it's a dead end, and no one can figure out why the images are no longer displaying properly. @PowerGlove you are our forum wizard. Can you shed some light on this?

That's an elegant solution.

This looks to be a server side problem, which i don't have full access to properly debug.

LoyceV had a great idea. It will work nice, no problem for me

I am involved in other personal projects and wasn't able to implement something like LoyceV did.

What would we have to do to make this a permanent solution? When you say less convenient, what do you mean? How would I update the data on the table?

Please let me know what you have in mind.

Correct. The "problem" is with updating links.
My server only reads HTML, so:

For me, the easiest would be a text file with a file name followed by it's URL. Example:
I can just parse this, and you can use whatever name you want. In your post, you'd use this:

If you don't do frequent updates, a simple text-file will do. If you want more frequent updates, it would be nice if you can upload it somewhere so I can automate checking it.
