[Suggestion] Make image name unique (maybe concatenate all params?)

[heldercabral]

Hello,

First thanks for this tool, I find it very useful to test the display of images in UI components. I have a small suggestion/improvement request:

Normally I save the image by dragging it out of the browser to a folder and every time I do this the image name is the 'Foreground Color'. Because I'm creating a lot of test images with different sizes I need to either change the name every time or change the foreground color otherwise windows will display the "File with same name already exists" popup message all the time.

My suggestion is that the name of the image should include more parameters like this:
600x400_000_fff.png

Thanks
