It’s a Squashfs filesystem, little endian, version 1.0. Unsquashfs had no luck with it, and I think this is due to support for version 1.0 being depreciated in kernel 2.6.29 (read this in a blog). I’ve tried firing up an old VM with a 2.6.12. kernel and following instructions to add LZMA support with no luck also.
If you have images that take up a large space on disk, you can reduce that space even without changing the image dimensions. The best image compression is achieved by using the JPG format, but even if the image is already in this format, you can usually still make it take up less space, as the JPG format has an adaptive compression scheme that allows saving in varying levels of compression. The trade-off is that the less space an image takes, the more detail from the original image you lose. You should also be aware that repeated saving in the JPG format causes more and more image degradation.
Since GIMP-2.8, images are loaded and saved as .XCF files. Your JPG image has been loaded as XCF. GIMP offers you to Overwrite image-name.jpg or File → Export As to open the “Export Image” dialog.
There are no visible compression artefacts.' — 9to5Mac Squash is a simple, powerful app for compressing and converting images for the web and more. Squash Features: - Drag and drop simplicity, single or multiple images supported - Reduce file size of images and photos for faster uploading - Compress JPG, and PNG without losing image quality. A single graphical image with translucency (Figure 2),. A web corpus: 12000 randomly chosen PNG images with translucency or not, crawled from the Internet. Spectrasonics omnisphere 2 0 3d download free. These PNG images are optimized via convert, pngcrush, ZopfliPNG and the smallest version of each image is considered for the study. Photographic image, 1024 x 752 pixels. Sep 05, 2017 Release 2.0.4 continues our work on ensuring Squash is one of the best image compression tools on the Mac, and if you don't already own a copy now is a great time to buy it To celebrate the impending launch of High Sierra, we're dropping the price for a limited time from $19.99 to $14.99 — Hurry this offer won't be available for long! By default, we compress JPEG images using a combination of lossy & progressive compression while reducing chroma sampling to 4:2:0. Our goal is to reduce JPEG file size at the highest possible image quality. This tool also follows the image compression guidelines set by Google. Why should I compress JPEG files?
Figure 3.22. “Export Image” Dialog
The dialog opens with the file name already typed in the Name box, with the default.png extension. Delete the existing extension and type JPG instead, and GIMP will determine the file type from the file extension. Use the file extension list, red circled in the figure above, to see the types supported by GIMP. The supported extensions change depending on your installed libraries. Quickkey 2 1. If GIMP complains, or if “JPEG” is grayed out in the Extensions menu, cancel out of everything and step through the Section 4.7, “Change the Mode”. Once you have done this, click . This opens the “Export Image as JPEG” dialog that contains the quality control.
The “Export Image as JPEG” dialog uses default values that reduce size in memory while retaining good visual quality; this is the safest and quickest thing to do.

Reduce the image Quality to make the image even smaller. Reduced quality degrades the image, so be certain to check “Show preview in image window” to visually gauge the degradation. A Quality setting of 10 produces a very poor quality image that uses very little disk space. The figure below shows a more reasonable image. A quality of 75 produces a reasonable image using much less disk space, which will, in turn, load much faster on a web page. Although the image is somewhat degraded, it is acceptable for the intended purpose.

Finally, here is a comparison of the same picture with varying degrees of compression:
