Looking for an app that will edit photos like Skitch

Question

This is probably the wrong place to put this but maybe I can get help with finding a better than app like Skitch for photo manipulating.
Skitch is close but there are a few things I don't like and find it hard to use for my purpose.
I like to be able to change file name, adding arrows with narrative, and resize using pixel count and not percent.
An example would be FastStone Image viewer for a PC. Actually this has much more than I need but it is a good program.
Thanks

What system is your MacBook currently using?
Some of the titles formerly available had not been updated to later OS X systems, and a few that I liked, do not appear to be available anymore from their authors source pages to download.
One I liked for a few years, went by the odd name 'ToyViewer for Mac, version 5.1.1' - free - & was in a 6.5GB download zip file. I saved the file but it was said to be for Leopard 10.5.x and a different one at the time was available for Tiger 10.4.11. Somewhere I probably still have a zip for the earlier Tiger version 4.x. in an archive.
There may be something out there that isn't a high-end image editor or image manipulator, at a fair price. Names like Acorn, Pixelmator, Graphic Converter, and then there's Gimp... are out there; plus a monthly fee to use some photoshop?

Years ago, I'd found I can resize, edit, rotate and whatever on the desktop of my almost antique Mac in the Finder, using screenshots. Also to view an image, I can open a browser (mine go nowhere on launch) and drop in the image; then pull the window larger or smaller and the image fits that size automatically. I can screen capture in Finder. And the saved captures are .jpg since I changed the default, because .png did nothing for me.
That method plus  'ToyViewer for Mac' (leopard version, may work in snow leopard) has worked fine for me. Beyond my needs, actually. And I've seldom used the included Image Capture application in the OS X, and manually save images from digital camera into folders, so I avoid iPhoto's intervention and storage ideas totally. Even though it is installed.
If I were in the area, I'd give you a copy of the zip for ToyViewer v 5.1.1. (Maybe it won't work in SL10.6.8.) It can do more than expected for what was a free license application by an author in japan. His page is gone...
PS: yes, the system default viewer, Preview, can do quite a bit.
And so do screencapture keyboard shortcuts in Finder.
Good luck & happy computing!
