EDIT: The Frame Extraction feature has been fixed. Easily a 5/5 recommendation.
Viewhance has a lot of functionality and fun features that all generally work well. Though my one gripe that keeps me from giving it a full five stars is that its frame extraction function does not work properly anymore thanks to more recent Firefox updates. If you left click and try to get full frames, you come back with nothing. Right click and it all comes out a glitchy mess. It's a real shame too because there doesn't seem to be any other add-ons with this sort of feature apart from Google Chrome's "GIF Scrubber".
i use this add-on as well as imagus. My only request is that you clean the Options page up. Every setting should have a "?" next to it and Clearly explain what each setting does when hovering over the "?". Then it will be a perfect 5 stars.
Would it be possible to add features that allows you to import as frames with the option of selecting multiple files, and export all frames? That's the only thing that is missing. Other than that, I love this addon.
Everything works perfectly! I just wanted to bring your attention to an issue in Firefox webextensions, you may want to keep that in mind and maybe test accordingly: ghacks.net/2017/08/30/firefox-webextensions-may-identify-you-on-the-internet/
The Imagus/Viewhance add-on is excellent, and by far the best hover zoom extension. It has better functionality, customization, and development than other alternatives (e.g. Image Zoom Plus, Image Zoom, ...), and it is not sleazy like those either (the others collect and sell your browsing information)! Also, it is available for both Chrome/Firefox, and very consistent across both browsers.
Does what it must. However with it's current most important basis elements it could still be improved.
Placing the icons over relative large images or next to relative small images when hovering to the side of the image reduces mouse travel path. Maybe it would be better to make the hover eactive at the bottom or top. Nowadays widescreen has become the standard and in result up and down mouse travel is relatively little.
Replace brightness and contrast with curve/level. Actually when nicely done the three could be incorporated with one icon. An option to have curve as one of the basis elements is really a must to have. It gives better control over other colour areas. Contrast reaches primairly only the lightest and darkest parts.
You're knocking it out of the park with Imagus and now you are hitting a home run with this extension. It is so handy to have all these tools at your disposal to edit photos just like a dedicated photo editor and it opens so easily.
You have made me not able to browse photos the same way ever again. I cannot use any browser unless I have your tools now.
