any chance you can add support for local files, ie images dragged into the browser "file://" ?
Add YouTube support
better than i could've imagine
I'm telling my photography students about this! These students are just learning to "see" the rule of thirds (and other elements) so they still very much need guidance like this. However, they simply aren't going to spend the time to save images posted in their group discussions and apply the thirds lines to the photos using another program or tool. This is something they can utilize right there on the discussion page without any extra steps, which means they'll actually use it.
Amazing this is so good.
doesn't work
Hi Team.. Its awesome .. Can i get grid of 5*5 .. or if u can help me how can i change it would be more helpful..Please can i get the grid of 5*5..
But black and white glow lines could be better. I am using it to learn drawing.
I love this extension. I wish it worked for videos too!
Программа хорошая и очень, как мне кажется, редкая. Хочу попросить, Творца или Творцов, сделать "Hot key" и настройку цветов линий. Спасибо.
