Q: Why I can't edit pictures in Sku Fetch?
A: When you click Edit and are first redirected to Pic Monkey (The App that permits image edition), they are explaining this in a pop-up. It is possible your browser has disabled Flash by default. You'll need to follow the instructions pic monkey shows and change the settings for Flash to "Ask First" and then when you try again, you'll get a pop up asking you to Allow Flash, you'll need to allow and then you'll be able to edit as usual.

You can also copy and paste this into your browser (do not click it, just copy and paste it on your browser) -->> chrome://settings/content/flash
And change the setting that says Block Sites from Running Flash to "Ask First"
And you can create an entry under the "Allow" section for Pic Monkey but adding this link there -->> https://www.picmonkey.com:443
Once done, it should look like this
And you'll be able to edit your images as usual.
