Here is an attempt to match the approximate location for the Huygens probe touchdown based on the PIA08114 mosaic and the surface image.
I’ll assume that the mosaic center is close to the Huygens landing site.
Here is the article that pinpoints the location of the probe landing site:
Karkoschka et al., Planetary and Space Science 55 (2007) 1896-1935. “DISR imaging and the geometry of the descent of the Huygens probe within Titan’s atmosphere.” doi: 10.1016/j.pss.2007.04.019.
A key section of the article is Section 8.5 – Terrain near the landing site
From the article: “The images after landing looked at a central azimuth of 193 degrees.”
Another portion from Section 8.5 from the article:
“In the SLI images of the landing site, the apparently flat area with rocks may extend to about 30 m distance, where the rocky area turns into an area without small features. This transition may be the transition from flat terrain to the relatively steep slope climbing almost 1 m across 1-2 m distance. If the furthest rocks visible are at a distance of 30 m, they are just about the same size as the rocks seen in the foreground. In the left part of the images taken from the surface, there is a bright, horizontal line between the end of the rocky area and the horizon. This could be the closer hill, while the horizon marks the further hill, some 5 m further away. These are our best guesses, while other guesses are equally valid.”
Another key sentence: “Note that the largest rocks of some 20 cm diameter seen on the ground are smaller than the pixel size of 30 cm in frame 716, or the PSF size of 50 cm.” Thus the cobbled littered portions would appear smooth to the DISR images.
So using the literature article and matching PIA08114 with PIA08115. (To give full credit, I think the authors of the Karkoschka et al. article were also responsible for the assembly of both PIA08114 and PIA08115):

For reference, the large paramecium-shaped feature at the center of the DISR image is about the size of a house.
