This seems status-by-design with IMGUR. That is when the size of the image reaches some threshold, conversion to JPG is automatically initiated. The threshold seem to be around 1MB.
Here is an external reference to a discussion on one of IMGUR's forums:
PNG file changes to JPG when uploaded

What changed is that we started using imgur thumbnails by default in chat; so when you link to http://i.stack.imgur.com/iSQFI.png, we display http://i.stack.imgur.com/iSQFIm.png, but link to the original:
<a rel="nofollow" href="//i.stack.imgur.com/DmZBd.png">

I think you should paste the contents of the pdf_tex file into your question. Then all the necessary info will be in the question itself, which is better than relying on external sites, in my opinion.
Note also that if you upload a PDF as an image to the post, it will be converted to PNG, I don't think the original PDF is saved.
I'm not a lawyer, and copyright laws differ from country to country, but in the U.S., copyright does not need to be asserted: it exists the moment you produce the work. So in reality there is no such thing as "unknown copyright"; the safest assumption is that it belongs to the author or has been transferred to someone else. That said, it seems to me that ...
There doesn't exist a native way of doing that on the network. However, as already mentioned in Schrödinger's cat's answer, you can use the image search option with Google, targeting this site via
Note though that this may only be valuable in select instances where posters did use images. Some threads only post an image in the ...

A shorter workflow is to submit screenshots rather than the actual pictures. You take a screenshot by pressing the "home" and "power" buttons simultaneously. The screenshot automatically goes to the camera roll, which can be directly accessed from Safari--it's the only thing you can get to from a conventional "upload" menu.
True, comments provide only a limited set of markdown features (actually referred to as mini-markdown) with no convenient image-inclusion technique.
The only way is to insert the image using the way described in how can i upload an image to be included in a question or answer? (that is, in the "Your Answer" box press Ctrl+G or via the GUI), copy the link ...
As of now, Stack Exchange only provides image uploader on all sites using Imgur's service.
While some SE sites got their customization like Code Snippet (SO, etc), MathJax (Mathematics.SE, etc), embedded YouTube video (SciFi.SE, etc), ABC notation (Music.SE)... but PDF uploader is not one of them.
The community of Blender.SE provides an unofficial way to ...
To second Torbjørn: It is strongly preferred to include content of your TeX file into your question.
But in almost all cases you should reduce the code to the absolutely necessary parts. This is called a minimal working example or short MWE. We have an own meta question here (see I've just been asked to write a minimal example, what is that?), and you ...
Maybe this could be useful for someone: the convert command of ImageMagick has an option which allows you to cut out the written part of an image: -trim +repage.
If you use arara package you may use a rule like this to do the conversion automatically.
For example if you have this myfile.tex (I've setted the background to red only to show the trimming):
Use Licecap. It provides the end user with "simple animated screen captures" and functions on all major distributions (Windows, OSX, Linux). Features include
Record directly to .GIF or .LCF.
Move the screen capture frame while recording.
Pause and restart recording, with optional inserted text messages.
Global hotkey (Shift + Space) to toggle pausing while ...
In the particular case of a beamer question with overlays, it is often useful to attach the output in the form of an (animated) GIF.
The answer to that (brought to me courtesy of @Schrödinger'scat) is that you can use convert from ImageMagick.org: convert -density <density> -delay <delay> -loop 0 -alpha remove multipage.pdf animated.gif, as ...
Looks like the problem was a certain browser extension: disabling it solves the problem. I have no idea why that extension, which has never created problems before, should do so now, but I'll deal with that later.
Thanks to Gypsy Spellweaver for the tip.
I experience more or less the same:
No matter what file I upload, the image https://i.stack.imgur.com/gGfsT.png is displayed:
I helped myself as follows:
I browsed to the page https://imgur.com/upload and uploaded my image-file there.
The file got uploaded and the uploaded image was displayed.
I clicked the image with the right mouse-button.
