On the subject of Korea…

On the subject of Korea, I visited South Korea about a dozen times with my previous employer. I have found some scans of photographs I had taken on one of my trips in February of 1986. I share them here to sort of let you know the type of war footing that the South considered themselves under.

Knowledge Base: Resizing Images

When you include an image in a comment or post with the “Add Media” button, you’ll be asked to select the size at which it will be displayed in a box at the right.  You’re usually given options like:

  • Thumbnail
  • Medium Size
  • Full Size

with the dimensions in pixels of each option shown.  The options shown depend upon the size of the image you uploaded.

The sizes available in the box are not your only options.  Once the image is included in your post or comment, you can click it, which will highlight it and display a series of “handles” which you can click and drag to resize or scale the image.  Usually, you’ll want to use the ones at the corners of the image, which scale the image preserving its aspect ratio (ratio of width to height).  Just drag the handle until the image has the size you wish to appear in your post.

There’s an important detail, however.  You should never re-scale an image to be larger than the size at which you inserted it, only shrink it to be smaller.  When you insert the image from “Add Media”, a pre-processed image of that size is selected.  If you scale it to be smaller, the user’s browser will scale it and no resolution will be lost.  But if you expand it, the smaller image will be blown up to the larger size and will appear blurry.  If in doubt, insert the image in your post at “Full Size” and scale it down to the desired size—this is the age of Extravagant Computing and few people will notice the inefficiency of doing so, while if you scale up a small image, it will look crude and ugly.

Knowledge Base: Including Images in Comments on Posts

When you’re writing a comment on a post and wish to include an image, it can seem puzzling, since the mechanism is entirely different from that used when you add an image to a main post.  Why?  Because the image facility for main posts is a WordPress built-in feature while the comment composition editor is a plug-in by a third party which does not conform to the same interface.  It would be nice if it did, but, not wishing to implement everything from scratch, we work with what’s available.  Once you get used to it, including images in comments isn’t all that painful.  Let’s dig into it.

You insert images in comments by clicking the icon at the right of the comment composition box that looks like a mountain range (that’s supposed to suggest a picture).  When it pops up, you’ll see the following dialogue:

Insert image dialogue

(The icon which summons this dialogue is shown at the top left, subdued.)

In the Source field, you enter the URL of the image you wish to insert.  That’s the Web address whence the image can be accessed.  You can use any image hosting service, but by far the best way is to upload the image to the Ratburger Media Library.  You do this, ideally before beginning to compose the comment (but if you forget, simply open another window, navigate to Ratburger, then use the New/Media item in the menu at the top left), by specifying the image file to upload from your local computer.

After you’ve uploaded the image, its URL at Ratburger will appear in the panel at the right of the window.  Copy it to the clipboard and dismiss the Media Library window.  It will look something like:

https://www.ratburger.org/wp-content/uploads/2017/12/insimg.png

which happens to be the URL for the image above.  That’s what you paste into the Source field of the Insert/edit image box.  The “Image description” field is optional, and specifies the alternative text displayed for users whose browsers cannot display images.  This is particularly important for the blind who use screen reader programs, but this is a courtesy and not a requirement.  The Dimensions will be filled in automatically and needn’t be changed unless you wish to resize the image.

If you upload a very large image (for example, a raw snap from a digital camera which you haven’t resized for use on the Web, the image will be automatically scaled to fit within a 600×600 pixel bounding box.  It is not possible to specify alignment (left, centre, right) of images within comments as one can for images in main posts.

Let me be the first to say that this is less than ideal, but it’s a lot better than what WordPress provides out of the box: no facility for including images in comments whatsoever.

In WordPress/BuddyPress posts and comments on posts have nothing in common with posts and comments in groups.  There is presently no simple way to include images in groups.  That doesn’t mean you can’t include images there, just that you’ll have to know how to type an HTML img tag into your message to embed the image.
