Recommended Photo Editor for Older Windows XP on Notepad

Yes, I know this is an old machine but it serves me well as a backup device when travelling. Can't afford a better laptop so am looking to optimize what I have.

It's a Dell Inspirion 1011 Notebook with an Intel Atom 1.9Ghz CPU and 1 GB of memory. Screen resolution is only 1024x600 which is too small for Vivid-Pix

I use a Oympus E-PM1 and take pictures in both RAW and JPEG. I've also started taking videos.

I found the Olympus Viewers (need V2 for my camera's video) too much for my laptop.

I've installed Nikon's ViewNX which has a smaller footprint than the Olympus viewer and can process JPG and works well enough. This is what I'm currently using.

I would like to get something that would process RAW but with the limited compute resources realize that this is not likely.

Is there a good web based cloud service that I could upload my files to for processing off my computer?

Looking for any suggestions.

Thanks

try faststone.org

Thanks Wolf Eel. I checked out Faststone and it seems to be useful but does not have a white balance eye drop control that I wanted.

In the end, I went back and revisited the Olympus 3 Viewer. They seem to have improved it by showing a lower resolution picture with an option to see the high resolution. OV3 has a white balance eye drop control for grey which I'll be able to use with my card. It will also Export in TIFF.

I also found Gimp which has a healing tool, stamper and other Photoshop like tools that I can apply to the TIFF.

So, I'm able to get some more life out of note book that I only use once or twice a year on dive trips.
