The app does not come with an installation kit, so AhaView is portable. In other words, the tool can be stored on a removable device, from where you can directly run its executable file on any computer.
More importantly, the Windows Registry is not updated with new entries and no files are left behind after program removal.
The interface of AhaView is dull and uncomplicated. Thanks to the Explorer-based layout, you can easily locate and access image files (‘drag and drop’ is not supported). Processing multiple items in batch mode is possible.
So, you can view a picture in full screen mode, and turn it into an icon by specifying the output directory and filename. In addition, you can edit a picture in the external image editor, change its file type (into BMP, JPG, PNG, GIF, TIF, TGA, or XPM), combine multiple pictures into one icon, rename and duplicate items, create a slideshow, and make file associations.
From the ‘Options’ area, you can change the default size of thumbnails, adjust the slideshow delay, change the background color in full screen mode, alter the size of the icons, and others. Settings can be restored to their default values.
The program has a good response time, quickly creates icons and requires a low amount of CPU and system memory. We have not come across any difficulties during our evaluation; AhaView did not freeze, crash or pop up error dialogs. Aside from its interface which needs a complete makeover, AhaView can be used with confidence by first-time and skilled users alike.
