Comments and Reviews
It's fast easy, relatively lightweight and it works. AND you can do selections with alt + 1 (2+3) which you can view with ctl + 1 (2/3)
Crap. Despite its solid age the program still has bugs of infant level. Example: I change the ordering of pictures in a folder. The thumbnails in the corresponding panel are reordered, but when I start clicking through pictures, it shows them in the old order! That is, the current thumbnail is one and the actual picture shown in the picture panel is another! The fact that developers still haven't fixed it can only mean they are imbeciles.
I am missing possibility to draw a rectangle with/without a fill in order to highlight or cover part/s of the image in order to hide sensitive parts or draw an arrow over the image to point to some detail.
It's technically possible to run Gnome applications on a Mac using Macports, or simply installing Linux on your Mac and running the applications natively from a Gnome session. Probably better to just wipe the Mac OS off there first, though, your computer will run better on Linux anyway.
That last line wasn't necessary, both of you. OP have a point there, it should have disclaimer about unofficial supported through other means. And SparkleenEnterprise response is the kind that makes our Linux community toxic. Don't try convince others by condescending them.
I don't know how often the top software package's description is updated, but gThumb hasn't been able to display .ICO files for years.
