Our forum is having problems displaying images. Sometimes they show, but most of the time they don’t. Not sure how to track this down, our image max display size is 860x860, max upload size is 4M. Here is a thread which shows the difficulties: https://forum.valentina-project.org/t/pngs-a-no-show/1964

svg is a quirky format, unless it displays fine in browsers I would not expect it to work at all, also you are going to have to whitelist the format.

Svg should not be expected to work in every scenario, because there are many security restrictions on the content. Focus on the regular binary images.

Unless you can repro the binary image issue here, I am not sure how much we can help.

Ok, since you know more about Discourse than I do, could you suggest points along the process where this problem might occur? If you don’t mind, could you walk through the process with me: File upload/storage: The files are uploaded properly, they exist and there are no errors in the files, they can be accessed manually, etc. File retrieval: Which Discourse processes retrieve these files? Which log settings could issue error messages about image file retrieval? File display: Which Discourse processes display the files? Which log settings could issue error messages about image file display?

Hi @sam, thanks for the suggestion, last night I updated last week’s release via terminal window (cd /var/discourse, git pull, .launcher rebuild app) and the problem still exists. We don’t use Amazon s3 storage.

[图片] slspencer: We use a lot of screenshots (.png, .svg) and other images to provide software support. I don’t have any explanations for your problem, but note that you can paste images directly into the composer. You don’t need to first paste into some other application to create and image to then upload.

Got the message that docker version not supported Installed docker-ce, now is my forum gone? After running the latest Discourse update a few days ago, clicking the the download icon opens .txt files in a browser instead of downloading them, yet no Discourse settings were changed. Yet now .png files are displaying properly. So a deeper problem is occuring. I implemented the Discourse/Docker periodic manual full update instructions and watched error messages. All updates .launcher rebuild app I received an error message that docker 17.05 is not supported, minimum required is 17.06.02. Ubuntu has changed the package name from docker-engine to docker-ce. Is it safe to install docker-ce, as this won’t be an upgrade? Because of the docker version preventing app rebuild, my forum is down. :frowning: What do?

Yes docker ce is what you want to use

I think before any of this, can you confirm you are using our official installer? Are you using s3 uploads or standard uploads? Have you ran:

cd /var/discourse
git pull
./launcher rebuild app
