There is a fairly workable solution right now using html, though I agree that a more intuitive method would be preferable. First, you have to upload the image as normal, and get the imgur link, for example. https://i.stack.imgur.com/m2uYu.png If you click on that, you'll see it's way too large. You can then include the image in your post scaled to any factor ...

In your special case we can get away with the built-in \triangledown to represent the lines connecting each vertex. We can also make use of \odot to represent each ringed node: \begin{array}{ccc}\hline\text{Case}&\text{Coxeter diagram}&\text{Vertex configuration}\\\hline\text{1 ringed node}&{}^{\boldsymbol p}\hspace{-0.15cm}{\Huge\triangledown}...

We prefer you do not ask a question using a photo of text. Instead, please transcribe it using MathJax. There are several reasons for this. Without text, the question is unsearchable, and it is unlikely another user with the same question will find it. The core principle of StackExchange is to provide help in a way that can also benefit spectators and ...

We already had users posting pornographic pictures, or stuff like that. I think that's a good enough reason. At the very least require someone to add something of possible value to the site before adding something very terrible.

"Very low quality" should generally be interpreted as "of such poor quality that it is unsalvagable." For example, VLQ is for unintelligible grammar, horrible/unreadable formatting, trolling, or content that makes no sense whatsoever. It shouldn't be applied towards posts whose only problems are with equations being images (unless the image meets the above ...

I get that too. Started noticing it a few months ago. The few I investigated seemed to be hosted "off-site", like the URLs for the <img> tag was on a Facebook server, or some non-Stackexchange place like that. Me, I've got all kinds of Javascript disabled and hosts blocked, so I figured it was due to that. Do you have any kind of blocking ...

Instead of using MathJax you can create your table in TeX and then export it as an image to insert into your post. It will display faster and uniformly in all browsers but won't scale since it is a raster image. See https://tex.stackexchange.com/questions/11866/compile-a-latex-document-into-a-png-image-thats-as-short-as-possible for exporting a document as ...

@Jyrki Lahtonen has specified one way to do so which is most widely used. I would like to add a more information : When using an <img> tag, any attributes must be specified in the following order else it will strip the tag and the image will not be displayed: src, width, height, alt, title. The values for the width and height attributes can be up to ...

While I agree that images of text or formulae are undesirable, I do not believe use of images alone is a good reason to close a question - I view closure principally as a tool to deal with questions where further input from the OP is required to make the question possible to answer well. This is not such a case - the appropriate community response to posts ...

It is not possible to make an image whose colors vary depending on whether the background is light or dark. The PNG* standard simply describes the color of each pixel, including an alpha channel; it has no provision for "responsive" images. However, there is a workaround: You can also use the inverse, black text with a white outline. The point is, ...

While editing a post, there is a button at the top of the editing pane: This button can be used to add images to a post. When you click on that button, it opens up a dialog which asks you to provide the URL of an image, or to upload an image. If you upload an image, it will be uploaded to imgur, then embedded here. As Math SE incorporates imgur uploading ...

Transparent png test: On white it looks like On black it looks like It doesn't "work" on coloured backgrounds:

I've just started working the Close Votes queue, so I am very interested in the reaction to this question. Currently I'm more likely to vote to close if the main question is in a screenshot, but I'm considering taking it on as a blanket policy. I probably will if the OP is highly upvoted. Additionally, I'm considering down-voting answers to such poor ...

There's not much that we can do except downvoting and closing their stuff with a comment that asks them to replace their text images with the appropriate text. When they've made the demanded changes, the downvote and close vote would be retracted.
