Image Handler 4 (for v1.5.x) Support Thread

[Zean]

The Github repo is updated for ZC 1.5.5.

Since I want to use IH with a fresh install of ZC 1.5.5a, which version of IH should I use? I have not used IH before.
I noticed on the Image Handler 4 for v1.5.x Plugin page, it says, "Zen Cart Versions v1.5.0, v1.5.1"
I'm guessing this is the link to the updated for ZC 1.5.5 version at Github https://github.com/DivaVocals/zen_Image-Handler you are referring to.

Should I use the version on the ZC Plugin page or should I use the version at Github?

Thanks so much!
