Web browsers show images at 72 dpi, period. If there's 720 pixels, the image will be ten inches. It's the nature of the beast.

You can resize a large image by putting height and width in the < img > tag, but this generally looks bad because the browser is resizing it, something they are not especially good at.

Also, if you're starting with 72 dpi and bumping it up to 300 in Photoshop, you need to realize that Photoshop is more or less just guessing at what the new pixels should be. You need to proportionately reduce the print size in Photoshop at the same time you increase the dpi.

If you want hi-res printing, make PDFs. Another approach is thumbnails with links to the large image. Computer-literate types can save the file, open it in Photoshop and print from there.
