When at 100% of size when placed in ID, a 72 dpi image is (more or less) a one-pixel to one-pixel relationship with your monitor's ability to display it. Unlike Photoshop, which will smooth out the view, ID tries to display those pixels in a way that is still useful, but may not be representitive of its output to whatever device or file type.
Try a quickie test. Export to a PDF. How does that image look?
Also, there are a couple settings that can affect the quality of the display. Under the View menu, and only when you desire to view a high-quality version of the ID file, select Display Performance | High Quality.
Take care, Mike
View > Display Performance > High Quality Display ( and it wouldn't hurt to right click the image and verify that it is using the display settings rather than its own).
Beyond that, keep in mind that waht you are seeing is a preview, not the actual pixels as you do in Photoshop. Some los of quality in the preview is not unexpected. Does it output correctly?
That PDF doesn't look odd for a low res image. What settings did you use in the compression section of the export dialog?
And how does it compare to a print from photoshop at the same size?
Thank you for showing the links panel, but could you stretch it downward a bit to show all the information?
Thank you, Mike
