gThumb may be available via your Puppy's Puppy Package Manager. Thanks to gychang's discovery of it on S15Pup64's repositories and to peebee's creation of S15Pup64 and solving the problem of how to get gthumb running, https://www.forum.puppylinux.com/viewto ... 968#p74968 it now provides to my S15Pup64 most of the capabilities which XnView offers debian/ubuntu based Puppys.
One of the reasons gThumbs can do that is its Right-Click options. Using it to file-browse to the file or folder you are interested in you can Right-Click a Thumb-nail of a graphic, then open that graphic in graphic editors on your system.
If lazpaint isn't already on your system, you can get it here, https://www.forum.puppylinux.com/viewto ... 021#p75021. Lazpaint is a 'near-universal' graphic format converter, even able to convert to and from webp format. It is the only graphic application I know of which enables you to 'mix' raster and vector graphics.
If you're into photograph, you should know that gimp has a filter for red-eye reduction. You can use MikeWalsh's gimp-portable, viewtopic.php?p=32465&sid=8accad7a3dad6 ... fd5#p32465. However, as packaged gThumb won't offer it as a Right-Click option. Mike's packaged it as a portable which can be launched from anywhere by Left-Clicking the included LAUNCH script. A Menu-Add script will create a Menu entry. But some applications can't work with the files Menu-Add adds to the system. gThumb is among those.
To use the combination gthumb and gimportable, use the attached pet rather than Mike'sMenu-Add script to create a menu entry. Unlike Mike's it requires the user to provide the path to the LAUNCH script.
After installing the pet, file-browse to /root/my-applications/bin and Right-Click the gimp script, select open in geany/Open as Text. As written, the second line reads:
exec /mnt/home/Pup-Apps/GIMP-portable64-2.10.25/LAUNCH "$@"
Change the path argument to that where you've located the portable folder; and use whatever name you've given that folder. e.g:
exec /mnt/PATH-TO-FOLDER/GIMP-portable64/LAUNCH "$@"
