Default Image downloads to JPEG via PDF print.

I use Flickr & similar sites where sometimes it's difficult to
download the images.

However printing the image to PDF and then converting this PDF image
to JPEG (or TIFF) gets results.

Is this final image the same quality as the Flickr one, and if not how
can this quality be improved?

that's a very roundabout way to do it.

probably not.

compare the original and the saved version and judge for yourself.

and if not how
can this quality be improved?


by resolving whatever the issue is that prevents you from downloading
the original image, which might be intentionally blocked by its creator
to prevent rampant theft.

It should have the same resolution as your display, not the original
photo resolution.

Although the printed version of a web page can be different from the
displayed version, and thus have a different resolution.


Maybe, instead of converting the PDF to JPG you can extract the
components of the PDF, and one of them might be the photo. But maybe the
PDF is just a single image.

that depends if it's printing a screenshot or the actual image.

for the latter, the display resolution is not in the pipeline and
therefore irrelevant.

it can, but not always.

that's even more convoluted.

If they belong to someone else downloading might be blocked.

This sounds like an awkward kludge, which guarantees nothing but mediocre results.

If downloading is 'blocked', you can usually still easily download the image.
In google chrome, you can press the F12 key to bring up the code for the
webpage and in that section in the top left there is a small icon of an arrow
in a square. If you click that icon, you can click somewhere on the site and
it will point you to the corresponding code.
So if you click an image, it will point you to the code for the image and
that usually includes the link to the image that you can right-click to open it
in a new tab so you can easily right-click the image there and download it.
Sometimes you need to search a bit in the webpage code (near the location
associated with the image) by clicking on the arrows to expand parts of the
code until you find the actual link to the image.
In the vast majority of cases, this method allows you to obtain the best
quality image, but there are also sites where this approach doesn't work
and you need other methods.

Thanks, this worked in a rough trial. I'll give it more use in the
future.

Pinterest, Internet images, but mainly Flickr.
EG this one on Titanic relics
https://www.flickr.com/photos/rollei...57600088149011
The Old Girl has been raked over rather well!

Extracting the PDF printout components gives a range of sizes.
Selecting them all seems to need a change in paper-size A2, A3 etc
with an orientation change. Many steps reqd.

I wonder what this means: "The owner has disabled downloading of their
photos”... Did you miss that?
