Without anakysing the document (only from the screeshot), your image is inside a frame and some padding space is allotted around the image (can be modified in image properties, Borders
tab.
Also, you image may be cropped. See Crop
tab. A different scale factor may apply to height and width.
Finally, have a look at Type
tab and the Size parameters, notably Keep ratio.
If this doesn’t allow you to cure the issue, attach a sample file with the problematic image to your question (not to an answer which wouldn’t be a solution to the problem).

EDIT 2020-11-04 - Answer to Dadasaur
Your sample file has several problems:
- wrong choice of anchor mode for the image considering its dimensions
- wrong size for the caption frame
- presence of a nonsensical drawing object
Apparently, drawing object Frame4 (not a frame at all) is not related to anything and can de deleted without changing document semantics.
Image Image4 (original size 40×26 cm) is scaled down 44% (to 17.6×11.4 cm) but is give a size of 17.6×3 cm in the Type
tab. It is anchored As character
which is an error with such a large picture. Being a character, wrap mode is pointless.
The consequence of these inconsistent settings is an area of 17.6×11.4 cm is reserved for the “character” but it is cropped to the first vertical 3 cm. Hence the red triangle for clipped content.
A caption has been added to the image-character (which is nonsense because a paragraph, the caption, cannot be inserted inline within another paragraph; it can only follow another paragraph) causing creation of frame Frame5 with dimensions 17.6×3.37 cm which is clearly too small. The previous inconsistencies prevent the caption to be visible.
To fix:
-
Change image anchor mode to To paragraph, wrap mode to None without Allow overlap. In Crop
, restore both Scale factors to 44%.
-
Change Frame5 properties to AutoSize in Type
, Wrap
mode to None without Allow overlap.
As a general rule, be very very cautious with large images.
