Featured figures in research project posts are in low resolution

[wehs7661]

Hi, I was working on the pages in the Research Project section that was built with the portfolio widget. However, I found that the featured figure (which was also shown in a thumbnail on the home page) was in pretty low resolution in the post even if the figure was actually of high resolution (600 dpi). To compare, I added the following lines in index.md to compare the resolution of the featured figure automatically put at the top of the page and the figure inserted by the lines:

<figure>
  <center>
  <img src="figures/featured.png" width=1000>
  </center>
  <figcaption> </figcaption>
</figure>

As a result, the featured figure (the upper one) apparently had a lower resolution. I'm wondering how I can possibly solve this issue. (The figure shown below is a screenshot, but hopefully still shows the difference.) Additionally, I'm wondering if it is possible to tweak the sizes/dimensions of the thumbnail shown on the home page and the figure shown in the post. Thanks a lot!

For those who are interested, one possible workaround that I thought of was using the following code to show the figure on the page and at the same time add preview_only: true for the thumbnail. See this discussion.

<figure>
  <center>
  <img src="figures/featured.png" width=1000>
  </center>
  <figcaption> </figcaption>
</figure>
