Another great feature is the batch editor. Many times I will resize and rename all of my photos before adding them to the blog, and batch editor is the quickest way to do that. You can even designate a new folder for them, which is great to help me stay organized in my blogging efforts.
I don't use Gimp as often because it is much more complex to use, however when creating images for my blog design, I have used Gimp a great deal. Any of the buttons, banners, or titles you see on my blog were created using a mixture of Gimp and Photoscape.
Before, I was not using RAW images for any of my blog photos, but now I do sometimes (because hubby got me a Christmas/Birthday/Just-Because-I-Love-You super awesome gift)!
So now that I am using my new camera and RAW files, I have just begun to use RawTherapee. It is supposedly similar to Lightroom (which I have never used, so I cannot vouch for the similarities.) There is another program called DarkTable which has much better reviews as being an alternative to Lightroom, however it is only available for Mac right now.
If you are a windows user, I'd say RawTherapee is the closest alternative you will find to Lightroom, based on the research I've done and reviews I've read. I have used it a few times, however I would not say that I've really figured out the features yet. Judging just from the looks of it, I do believe after I've read some tutorials and played around with the program that it will be very useful for editing my digital photos.
Like I said on this one I really haven't mastered any techniques, however I do find it to be a promising program.
What are your favorite photo editing programs? Have you ever used any of these three?
