I am a very recent convert to Linux, and the computer-person who presided over my conversion recommended Puppy 4.3.1. (Ironic because I am a cat-person, benevolently indifferent to dogs.) So, that I have; and so far, I am happy with it. I do, however, have one problem, and I hope experienced/advanced users can tell me how to solve it: In Windows, changing jpegs tp bitmap, or vice versa, and manipulating image balance in jpegs, were easy to do. I wish to do this with Puppy 4.3.1, but the people at the shop where I was converted to Linux, have not yet thewmselves figured out how to do this. Would someone knowledgeable please advise?

Thank you.

The premier tool for image conversion in Linux is ImageMagick -but it si a command-line tool. Not sure if the version you are running has it. You can find out by running this command in a terminal:
which convert

If it returns something like:
/usr/bin/convert
you are 'in the money'.
convert img.jp img.<nearly any image format>

There are also GUI image programs in Puppy(depending on version). They support less options, but usually just open the file you want to convert and then choose File >> Save As and choose the format and name you want to save it as -it won't remove the original(neither will the ImageMagick tool 'convert')

Urban Hermit,

Welcome.
Most versions of Puppy have mtPaint. For individual images it is one of the quickest ways of either resizing or changing the format. Load image. If you need to resize, go to Image, 'Scale Canvas', input new size - perhaps 800, or 1024. Then, after resizing, File, Save As. Use the drop-down menu File Format to input the required change and, if jpg's, the quality.

If you require more extensive capabilities, download and install XNView with it's dependencies.
