Requested Thumbnail size quick change

[Kultag]

Hi

I usually use IrfanView's thumbnails to look for identical pictures in a folder (car photos). I temporarily rename them so the same ones would come after each other and then delete others than the best. For this I need an optimal thumbnail screen in which the thumbnails are sized that they are the biggest possible, but ALL of them are visible. So I change thumbnail size usually. I would really like a quicker way to do this than going in the menu and change it. Two arrows (+ / -) would be enough. Or (as suggested by someone before) control+scroll would be OK as well. No need for an auto-optimizer I guess.

Another things: there should be the possibility to ignore files for which it can't show a thumbnail so they wouldn't take up space in the screen.

Opinions?

If you wish to ignore file formats to be shown in browser mode you should load only associated types. This option is to be checked in Properties/Settings/Extensions.

I just updated from 4.10 to 4.20 and I didn't change anything in the settings and now it's working properly. Is this possible? Maybe when I updated to 4.10 it was associated with everything in the list, and now only with pictures. Then I pressed the wrong button at the installation of 4.10. Anyway, it works nice now. Thanks.
