How to open my gif files on my computer. I am searching for lot of software's but I didn't find out. Any software is there open from Gif files.

I want software for Gif files?

As far as I remember InViewer can do that, at least it was capable before. Plus you can just drag and drop your gif file to Mozilla Firefox and it will be opened over there perfectly.

IrFanView is a good and popular freeware that will open almost all graphics files.

I second Irfanview. When you install it there will come a point where you choose which types of files to associate with it (files you associate will have an irfanview icon in front of them from that point on and will open in irfanview with a double click). Irfanview can open video and audio files as well so there is a selection you can choose for images only that will keep the selection list shorter. If you also use photoshop or another image editor you may want to not select those for irfanview (jpg jpeg etc.) so you don't end up re-associating those types of files away from your editor.
