Most of the posts on this site include a gallery of images and a link to a PDF file of those images that you can download.
The gallery shows only thumbnail images — usually 400 or 800 pixels wide — that give an impression of the image but not the best experience of it.
I have made the linked PDF files, however, to display the images at a full-screen size on either your computer or tablet with better framing and full control of the layout of captions and other information.
Please download the PDF files (I keep them as small as possible) and view them at full screen size. The best viewer is the Adobe Acrobat viewer which is available in a free version from Adobe.
If you use another PDF viewer you may find that the full-screen display is called “slideshow” or something similar.
