Image quality of photos is of particular importance on this one project I'm working on. Images are being rendered on very large displays are being compared for quality. It I needed to upgrade my software that would allow me more control of how images are imported ... which would you recommend?
I think we are going round in circles.

If you have high definition images then bring them into XWDP as I described in Post #2.
If the original image was 2560 x 1600 px then Xara will render at 96 dpi. The result is an image that is 26.67 x 16.72 inches, big enough for most monitors (and I know monitors have their own dpis).

If you simply drop the image onto a web page, Xara presents the image as 500 px Wide (I think, in my application, I tweaked the registry to bring images in at 1024 px Wide). This is 368 dpi.
if you then hit the 100% icon, will the image be displayed at 96 dpi. The pixel dimensions are, however, 1920 x 1204 px.
When brought back to the original dimensions, the dpi is only 72, so someone in Xara thinks were are using Apples (Windows uses 96 dpi/ppi).

You are right, if you try to scale up an image beyond its original dimensions, you lose quality.
No need to get another program.

To the specific problem you have, you are importing four images and scaling them to 500 px for their presentation.
When Xara builds the site, it renders the 500 px Wide image at 96 dpi.

There is a fudge you can use and develop.

Import your images as I described but into a separate Layer (Let's call it Photos) and ensure each is at 100% scaling (96 dpi).
For each image give it a Name of filename=PhotoA, filename=PhotoB, filename=PhotoC and filename=PhotoD (Utilities > Names).

Create a small box with a Link to the Photos layer and hide it under something else on the MouseOff layer.
This allows you to hide the Photos layer but still publish the full-size images.
There are other ways to achieve this but this is the simplest.

Now, on the MouseOff layer, create a rectangle the dimension of your image: 500 x 313 px for my example.
In its Placeholder HTML code (body), add the following:
<img src="index_htm_files/PhotoA.jpg" width="500">
If you now publish, the Placeholder will present the original resolution of the image.

Full Size Photos.xar is my demo - don't click the red box!
Oh, go on, I know you want to.
