10.2.8 here. Works well. Slim and fast. Good GUI. Suggest adding two features and an option:
Feature #1 -- Right/Command + Click to open image in user-defined image editor.
Feature #2 -- Ability to copy XHTML image tag to clipboard. This feature might include user option to format tag by altering default text, adding/removing attribute variables like height, width, filePath, etc.).
Option #1 -- Ability to change double-click so it opens image in pop-up window instead of main viewer. More likely to supply a full-size view of images more often.
Best of luck with future development ....
