Does exactly what is advertised. Tooltip display of info is especially useful to me.

Works very well, thanks

So damn useful. Works like a charm. Thanks a lot for coding and sharing such a handy little extension.

Appréciation en Français (English below) Je viens d'installer cette extension, à première vue elle remplit son rôle à la perfection. J'ai choisi l'option pour que l'info suive mon curseur, très pratique pour vérifier la taille d'une image sur une page en construction.

(English) Just start trying this extension and it seems to work perfectly. The information even can follow the cursor.

Quick, simple, useful

Excellent add-on! Special thanks for the"minimum resolution" option.

Simply awesome, thank you so much!

Possible improvement:
I would love to copy the shown text to my clipboard - or even better: Add a clone of the "Data JSON" settings field, to configure the values to copy on click.

And yes.. click wont work for all position-options.. but adding an additional copy-shortcut would solve this?

Все четко работает

Excellent replacement for the deleted "view image info" contextual menu item.

Excellent extension, information on the image can be obtained much faster than the built-in tools in firefox. A small wish - if the information on the image is displayed in bytes, then classes can be separated by spaces, for example, "42 085 540 B".

You really can't judge a book by its cover(or its number of users). This is the one I'm looking for for my android firefox since there's no option where you can see the image data. Thank you very much devs is all I can give you for now. I hope you best and be safe.

delay option please.
I want to place the cursor on the image for a while and show it only when I wait a few seconds.

Edit: thanks for delay option in new version.

It is possible to have the cursor X and Y position pixel of the image, I will contribute !

То elle2:
Button "on/off" now there is! ))

To cubeleco:
I would like to have the option "Follow cursor Bottom".

While I was able to achieve only "Fixed Bottom":
bottomleft: position: absolute; top: 91%; color: white; background: #07ac; font: 15px arial black; border-radius: 15px; padding: 10px 10px 10px 10px; text-align: center; text-shadow: 2px 2px 2px #000; opacity: 0.9;

Can you help me?

Need: a bar at the bottom of the window follows the horizontal position of the cursor.

So the panel will not overlap the controls web sites (usually located at the top or left) - how does the mode "Fixed".
The current mode of "Follow cursor" (when the panel is near the cursor) uncomfortable when using other add-ons (URL Tooltip WE, Link Alert) - they overlap each other.
Mode "Over image" is not convenient for small image - overlaps a significant part of the picture.
Mode "After image" is uncomfortable for bigger image - panel is often in the invisible part of the web page and needs to scroll down.
The mode "Before image" is not working fine when opened separately the big picture - the picture overlaps the panel, and centered the text is not visible. For test: https://img-fotki.yandex.ru/get/877700/9261163.19/0_9e522_278bb01b_orig
And at least on one site, this mode is buggy: http://nearspace.ru/ there are a few small pictures in a row and the bar starts to jump up and down.

So I want a versatile option. ))

This is perfect! Thank you very much!!!

Now cosmetic remark: when I change the page zoom, the scale panel is also changing. It would be nice to fix it (if possible).

Thanks again, cubeleco! I am fully satisfied. ))

Here's the final version (if someone is interested):

"Follow cursor"
bottomleft: position: absolute; top: auto; bottom: 2.5vh; color: White; background: CornflowerBlue; font: 2.2vh arial black; border-radius: 0.5vw; padding: 0.9vh 0.9vw 0.9vh 0.9vw; text-align: center; text-shadow: 0.15vw 0.3vh 0.15vw Black; opacity: 0.95;
