Alternative to IrfanView

Solution 1:

As a long time user of IrfanView myself, I was also looking for a worthy successor on Linux.

I have not found a single app for all my use cases, but I am happy with combining a couple of tools.

For adding basic info (e.g. arrows or text) or in order to obfuscate parts of an image, I use GIMP.

For other basic manipulation like cropping, rotating or color adjustments I found gThumb.

Solution 2:

I use Geeqie as a fast viewer (it can rotate and flip though), and Screenshot-Tool Shutter as minimalist Editor that can blur, crop and put markers into a picture.

With Geeqie I can say ("Open in external editor...")

Don't know how well this works under Kubuntu though.
